If you need a healing skill, just visit him again after defeating Migo who is in the beach close-by for his restoration ring.
It's just really easy and fast to just buy the beer from Grief or whatever npc in Fort joy for a few gold and visit Leste right away for the exp and sparkler without having to do anything else first. The quick 240 EXP is only worth doing for the level 1 to 3 rush where you only need to proc the EXP bonus once.
