I made a magician and i dont know what to do im lvl 11 because i joined catacombs and just sat there

Buy an enhanced effect accessory heal charm
and heal mastery weapon/armor/charm or int weapon/armor/charm

no clue what ur talking about lol i dont even know whats what in the game

Weapon: Heal Mastery (so you can heal party)... or Intelligence (not as effective to healing than Heal Mastery)
Armor: Heal Mastery (so you can heal party)... or Intelligence (not as effective to healing than Heal Mastery)
Charm Slot: Heal Mastery (so you can heal party)... or Intelligence (not as effective to healing than Heal Mastery)
Acc Slot: Best Enhanced Effect: Focus Heal or Heal or Wild Heal

That is the setup for a healing mage in catacombs...
The Acc Slot charm should also be in conjunction with your level

Character level 20... Acc Slot healing charm should be level 20 also
Character level 30... Acc Slot healing charm should be level 30 also
Character level 40... Acc Slot healing charm should be level 40 also
etc...
