Relic/Striker Button
I generally hate the placement of the button itself, I’ve repeatedly pressed just a little too close to it in order to parry, for the game to completely ignore my input.
Have a champion without the relic and the area is free to press.
Secondly, The button itself ignores me during certain stages, the timing a relic is ready is different to specials for example, the defender has to have fully recovered before you can use it.
Perhaps graying out the button itself during this process would help.
