Duplicate heroes and leftover fragments accumulate naturally as you play, and most games in this genre offer some form of exchange or conversion system — knowing how to use it well avoids leaving real value sitting unused.
Check exchange rates before converting anything
Conversion systems don't always offer a straight, even trade — check what you're actually getting for what you're giving up before converting fragments or duplicates you might have used differently.
Prioritize converting heroes you'll genuinely never use
It's tempting to hold onto every hero "just in case," but a duplicate or low-priority hero sitting fully unused provides zero value compared to converting it into fragments or currency you can direct toward a hero you're actually developing.
Don't convert away pairing potential too quickly
Before converting a hero, double check whether they have a pairing skill relevant to a hero you're actively developing — see our pairing skills guide for more on this. A hero that looks skippable solo might still be worth keeping for a pairing bonus.
Make conversion part of your regular routine
Rather than letting duplicates and fragments pile up indefinitely, a periodic review — monthly is reasonable for most accounts — keeps this system from becoming another source of quietly wasted resources.
