Tiles Survive is adding a Hero Skill & Signature Weapon Exchange event that lets players reorganize expensive hero progression without rebuilding every investment from zero. The feature supports Hero Skill Level Exchange between eligible SSR Heroes and Signature Weapon Level Exchange between eligible weapons. Both exchange types can be used multiple times, while promoted SR-to-SSR Heroes such as Lucky are excluded.
The most important advantage is flexibility: eligible Heroes do not need to share the same Faction, Class, or Hero level. That makes the system useful when replacing an older core Hero, changing faction focus, or moving Signature Weapon progression toward a Hero you expect to use long term. Exact event costs, weapon eligibility, and any event-specific limits should always be checked in the active event interface before confirming a swap.
What Is the Hero Skill & Signature Weapon Exchange?
The exchange feature is a targeted progression swap. It does not function as a full Hero conversion. Instead, it focuses on two specific development systems: Hero Skill levels and Signature Weapon levels.
Hero Skill Level Exchange: Select two eligible SSR Heroes and swap their current Hero Skill levels.
Signature Weapon Level Exchange: Select eligible Signature Weapons and exchange their weapon levels.
Multiple Exchanges: Both Hero Skill and Signature Weapon exchanges can be performed more than once during the event, subject to the rules shown in the event interface.
This makes the system especially valuable for established accounts that have already invested heavily in older Heroes. Rather than leaving high Skill levels or weapon progression on a Hero that no longer fits the main lineup, the exchange can redirect that progression toward a stronger long-term choice.
Which Heroes Can Exchange Skill Levels?
Hero Skill Level Exchange applies to eligible SSR Heroes. The two Heroes do not have to match in Faction, Class, or Hero level, so the system can be used across very different team setups.
Both selected Heroes must meet the SSR eligibility requirement.
Faction does not need to match.
Class does not need to match.
Hero level does not need to match.
Heroes promoted from SR to SSR are excluded. Lucky is a stated example of this restriction.
The promoted-Hero restriction is important because rarity alone is not enough. A Hero that began as SR and later became SSR through a promotion system does not become eligible simply because the current rarity label shows SSR.
How to Exchange Hero Skill Levels
When the exchange event is available on your account, the Hero Skill portion follows a straightforward selection-and-confirm process. The exact placement of buttons, costs, and event-specific limits should be read from the active interface, but the core exchange is based on choosing two eligible SSR Heroes and swapping their Skill levels.
1. Open the Hero Skill & Signature Weapon Exchange event when it appears on your account.
2. Choose the Hero Skill Level Exchange option.
3. Select the first eligible SSR Hero. This is usually the Hero whose current Skill progression you want to move away from.
4. Select the second eligible SSR Hero. This is usually the Hero you want to prioritize in your current or future lineup.
5. Review the displayed exchange result carefully, especially the Skill levels on both sides.
6. Confirm only after checking the event cost, remaining exchange opportunities, and the before/after values shown on screen.
Do not treat this as a full character swap. The announced exchange scope is Hero Skill levels. Hero level, Star level, Hero Gear, fragments, and other progression systems are separate unless the event interface explicitly says otherwise.
How to Exchange Signature Weapon Levels
Signature Weapon Level Exchange works on the same general idea, but the progression being moved is the weapon level. Only eligible Signature Weapons can participate, so do not assume every unlocked or owned weapon will automatically qualify.
1. Open the exchange event and choose Signature Weapon Level Exchange.
2. Select the first eligible Signature Weapon.
3. Select the second eligible Signature Weapon.
4. Compare the current levels and the displayed result after the swap.
5. Check any event cost or eligibility message shown in the interface.
6. Confirm the exchange only after verifying both weapons and the resulting levels.
The weapon exchange is most valuable when it moves a meaningful level advantage onto a Hero you plan to keep in your main lineup. A temporary Power increase is less important than placing long-term weapon progression on the right Hero.
Signature Weapons currently have a maximum level of Lv.15. Each Hero has a unique Signature Weapon skill, and that skill receives additional enhancements at Lv.10 and Lv.15. These two milestones should be part of every exchange decision.
For example, a swap that places a weapon at or near Lv.10 or Lv.15 on a long-term core Hero can be much more valuable than moving a few levels simply to raise the displayed Power number. The value comes from both the weapon stats and the additional skill effects unlocked at those milestones.
Maddie's Tempest Crossbow is one example of a Hero-specific Signature Weapon. Different Heroes have different Signature Weapon effects, so the best target for an exchange depends on the Hero's role, lineup value, and the exact weapon skill being improved.
What Does the Exchange Actually Change?
The safest way to understand the system is to separate the confirmed exchange scope from other Hero progression. The feature specifically names Hero Skill Level Exchange and Signature Weapon Level Exchange. Other development systems should not be assumed to move with them.

The main advantage is therefore the ability to redirect expensive Skill and Signature Weapon investment without requiring the two Heroes to belong to the same Faction or Class.
When Is an Exchange Worth Using?
An Older Core Hero Is Leaving Your Main Lineup
If an SSR Hero has high Skill investment but is no longer part of your main combat plan, that Hero can become a strong source for an exchange. Moving the progression is more efficient than leaving valuable levels unused while developing a replacement from the beginning.
You Are Changing Faction or Class Focus
Because eligible Heroes do not need the same Faction or Class, the feature is useful for larger lineup changes. You can redirect Skill progression even when the replacement Hero belongs to a completely different team archetype.
A Signature Weapon Swap Reaches a Key Milestone
Lv.10 and Lv.15 deserve special attention because Signature Weapon skills receive additional enhancements at those levels. If an exchange places a long-term core Hero at one of these milestones, it can create more practical value than keeping the higher weapon level on a Hero you rarely deploy.
What to Check Before You Exchange
Long-term lineup value: Make sure the receiving Hero is a real core choice, not a temporary event pick.
Current Skill levels: Compare both Heroes before confirming so you do not accidentally move stronger progression in the wrong direction.
Signature Weapon milestone: Check whether the swap helps the target weapon reach or approach Lv.10 or Lv.15.
Weapon eligibility: The exchange applies to eligible Signature Weapons; verify the two weapons are accepted by the event.
Event-specific rules: Review the displayed cost, remaining exchanges, timing, and confirmation screen before completing the swap.
Other progression: Do not assume Hero level, Stars, Gear, fragments, or other resources are included unless the event interface explicitly lists them.
A good exchange should improve your account's long-term structure, not just produce a short-lived increase in Power. If both Heroes are still heavily used, or if you are unsure which one will remain in your main lineup, waiting can be better than immediately moving progression.
Notice: Always compare the current Skill levels before confirming an exchange.
Common Mistakes to Avoid
Trying to use an SR-to-SSR promoted Hero such as Lucky.
Assuming two Heroes must belong to the same Faction or Class.
Expecting a Hero Skill exchange to move the entire Hero build.
Assuming every Signature Weapon is eligible without checking the event interface.
Ignoring Lv.10 and Lv.15 Signature Weapon skill enhancements.
Confirming before reviewing the event-specific cost and before/after values.

Conclusion
Hero Skill & Signature Weapon Exchange gives Tiles Survive players a practical way to reorganize costly progression when a lineup changes. Eligible SSR Heroes can exchange Hero Skill levels without matching Faction, Class, or Hero level, while eligible Signature Weapons can exchange weapon levels. Both exchange types support multiple uses, but SR-to-SSR promoted Heroes such as Lucky are excluded.
The best exchanges are planned around long-term roster value. Move progression away from Heroes you genuinely intend to bench, prioritize Signature Weapons that strengthen permanent core Heroes, and pay close attention to Lv.10 and Lv.15 weapon milestones. Most importantly, review the active event interface before confirming, because costs, weapon eligibility, and other event-specific conditions are displayed there. Used carefully, the feature can reduce wasted investment and make major lineup changes much easier to manage.
