Shouldn't be too much unbalancing. If anything should give your a small boost in any fight/craft/gather. And when you die you lose it and gotta wait 7 hours.

Some Draw's are really rare & random so its very unlikely many players would stack and use it.
Mainly its for crafters,noobies exping and coming across them,gatherers and restoring some anima.

Odds of each group is listed so players often get same buffs and very few get the rare buffs.
