Andor's Trail

Those 3 abilities, to me, are useless.
I mean: even if attackers gave me those "sickness", i also have enough bonemeal to cure me.
More, those abilities scale till 7th level, it means that require A LOT of Experience Points to be reached.
Really, i don't see any vantage in those abilities.
Someone is used to collect them? if yes, what is its strategy?

you know that the use of bonemeal is prohibited, do you?

A am not a kid anymore! i killed a rat or two, I can handle myself!

I think they were added mainly for the players that have reached very high levels, so that they at least have some skills they can still acquire.
