Celtic Heroes

Imo drop sneaky. It has a very slow reload speed and since you are leveling with a druid you will probably have most of the agro so you will be unable to cast. I would use poison weaps instead of it. People complain about it slow cast time but adding 100+ damage to every auto for 2 mins, even if poison is resisted in tower, still adds a lot more damage. It becomes even more useful if you find yourself leveling with a ranger or warrior as you can cast on them also.

Also for carrow leveling a dex build is much better imo however for tower leveling str is best so i would add more str if i were you.
