dude, poison sux , really...since lvl 8,9 i fight in 'the_den' against 3 opponents all time
when at lvl 9 i reached expertize with boars and humanoids,with lvl modifier i was hitting them for 33 damage with simple attack , critiacal goes to 65 damage... and all in all , i was losing around 50 hp per battle and gain was 60 exp...
i doubt poison is worth because my 1 simple strike at enemy is more than all damage your poison deal...
now with me on lvl 10 and increased agility more.. i lose around 30 hp per battle in the_den against 3 opponents what i recover in 12 min of time
....
now i changed place where i fight , i gain 45 exp against thief ranger lvl 12 but i lose half hp what i recover in 30 min...
With your poison and no points in herbalism you need to rely heavy on health potions and food... once you reach lvl 10 , 11, you would not be able to fight against your lvl enemies but you will be still fighting small lvl enemies. Also , once you attack high lvl enemy he will kill your half hp , witch you will regenerate in 14 hours while same amount i would generate in less than 1h time
Also one of reasons i am fighting againt ranger lvl 12 that give 45 exp and not back in village against 3 board that give 60 exp where i lose 60% less health is because here is likelyhood that this ranger will drop some high lvl item
... you will be still getting from these low levels lvl 5,6 armors and weapons...
