Bring a temple wand (or crystal wand, if you like the longer range) and a regular T11 wand - You should be able to tackle most opponents with these two wands, as the tiered wand is a good utility wand, and the temple/crystal can be used to take on opponents with higher defense. The tome is up to you- if you can control the speedy effect, use t6, otherwise, use tier 5. As for the robe, go with the silk robe. I have it on my priest, and the boost to speed and attack are very practical to have. There’s almost no situation where the lower defense from the silk robe would be a detriment, especially since you’re playing on a healing class. Good luck, and play safe!
Edit: Ah, forgot the ring. Expo is a great ring for balanced play. If you have a more offensive playstyle however, I would use an HP ring, or a MP ring so you have more hp or heals to rush and go deep.
