You wont find any + lock pick accessories from chests or merchants. The only +1 lock pick necklace is from Jagon in temple of doom, looted from his loot bag after he dies. The necklace is needed to complete the "Wanted" quests in broken valley. If you decide to keep it, then you wont be able to complete the quest
Skill points is usually enough even if you decide to max your lock pick in the early days. You just need to determine which is your major skill and focus on that few skills. If you are playing a pure mage, which my pure mage definition is not relying on weapon at all with just spamming magic skills only, your main dps skill should be magic missile. I try increase rank for both magic blast and fire ball to 13, where their cd is still stuck at 15 secs. So ironically magic missiles is the best skill you can spam with only 1 secs cd. And you wont need weapon mastery at all and that will save you up on a lot skill points.
