So how exactly are relics helpful when they take so long to activate?
In most fights even at Threat Level 5, fight is already over before the relic is activated. The time it takes to activate should be halved at least so that every 10 strikes (either you hit or get hit) it should be ready to deploy.
And when it does activate it has to do much more than just stun the opponent, or the supposed buff needs to be really felt and not some pseudo psychological placebo effecr thinking that the relic actually didnmor than just stun the opponent.
