really like mugger, but i would put a "penalty" to steal less than normal way, so you could use it just for that (or maybe let the first item you steal, make it 100% posible to be stolen, but then you cant steal anymore from that npc)
speed drinker i love it! both ones, maybe if let you drink heal just recover half of the flask. ( this will be for battle or turn? i mean the free ap)
