Stat Fusion

Can be found on the Modify screen of The Armory, after selecting an equipment under the Modify tab.

It allows you to increase the base stat rolls of a Legendary gear, by sacrificing a different Legendary or Peerless gear of the same template + slot. In other words, cotton shoes can be fused with all other cotton shoes regardless of prefix/suffix, but not with phase shoes or cotton pants.

For each stat, if the equip being sacrificed is Peerless or has a base stat higher than the equip being fused, the stat is increased by +2. Otherwise, it is increased by +1, and requires a core corresponding to the equip being fused.

If any of the stats are already capped, it will add +1 overflow point for each capped stat. These are redistributed to uncapped stats in order of lowest base. Stats can get multiple overflow points if there are more capped stats than uncapped stats.

It will charge 10 bindings for each stat being upgraded - that is, per fusion, not per point. It also charges a fixed number of credits per fusion based on the type of gear being upgraded and its average base stats. If you are missing any cores, it will add the equivalent number of credits instead, just like for upgrades.

Fully fusing a Legendary piece of equipment to have 200 in all base stats will change it into a Peerless. There are no differences between natural-born Peerless equips and fused post-Legendary Peerless equips.

Note that if you statfuse gear with a "legacy name" (i.e. equipment converted from the old system with a name that doesn't exist or is different in the new system), this name will be cleared if you fuse it to the point where it changes quality tier.

Certain hath perks will be added that also allow you to upgrade Peerless gear further. You can still sacrifice Legendary gear to fuse these, but the same rules apply. In other words, if sacrificing a Legendary, every stat increase will be +1 and require a Peerless core; if sacrificing a Peerless, every stat increase will be +2 and will not require a core.
