Echo Grotesque Guardians - The fight isn't meant to be the exact same as the regular fight, but putting that aside:
Dusk hits way too hard and hits through prayer (melees 35s through prayer and his ranged attacks on final phase hurt too)
A simple fix would be to let both be able to be hit by any style if you don't want to re-program the whole fight to be like osrs' echo gg fight
The gloves are nerfed and don't boost barrows set effects anyway so I think the above should be a nice compromise (was this also a design choice or was it left out?)
