Copy meaning it works the same way. Like, even Town poison and scum poison works differently. Stargate takes 2hp and other poisoner killed fang in 2 cycles. Assuming it's separate since Stargate said be didn't use it. York was roleblocker and i think worst was half roleblocker half rolecrusher or whatever. No other ability afaik is exact copy when it comes to effect. Jaguark has superkills while crying has temporary hp removal, etc. You get my point.
It's not the entire point of suspecting you but sure thing it doesn't help your case. I haven't commented on +HP because it's not a thing i have issue with. But even if so, idk why noone was notified they got HP. I got informed when i lost HP. When i vote silence people, they're informed too.
