What a Tarstone changes
A Tarstone is not just a passive collectible. Its slot, trigger and level effect determine whether it supports your weapon loop, survivability or resource economy.
Build a small test
Equip one change at a time and test it against the same enemy type. This makes it clear whether a benefit comes from the Tarstone, Shell ability or weapon.
Database caution
Launch databases are still filling gaps. Names and broad functions are useful now, but exact counts and some high-tier values need in-game confirmation.
