That build would be good for a more party-oriented cleric, but if you plan on soloing more, go with tele and MP Eater first. As for the rest of the build, I really can't say anything since I've never gotten a cleric to 3rd job. Though you should note that the build that gives the most % per hour would do nothing but pump Genesis until it's maxed, if you can afford it.

Does Elemental Reset take away the boost from ele wands? It seems logical, but I haven't seen it proven anywhere.

There's no reason to be a "party-oriented Cleric," nor has there been since Zombies came out. Tele and MP eater should be maxed first, so that you can train/PQ without spending a single pot. Nowadays with ZLupins, Master Chronos, H/Voodoos, and MP3 Clerics are one of the fastest levelling 2nd job classes.

Even if you're PQing, Tele and MP eater are still more useful than Bless and Invincible. The biggest asset a Cleric has is Heal. Every imaginable situation where people might want a Cleric involves you spamming Heal, MGless. Invincible is completely useless until late 2nd job, because you will be constantly recovering to full HP. Bless is a joke. No warrior relies on Bless to hit things anymore. If they do, they're a dumbass. The defense is garbage, and the avoid is useless for the same reason Invincible is useless.

tl;dr Bless and Invincible do not help you in any way in 2nd job. The earliest they become useful is at late 6x if you're training at Himes with an attacker, so max them last.

3rd job build looks good, 4th job build looks ridiculous o_o Infinity is the worst skill in your entire skillbook. Even when maxed it's only going to give you free MP for 1/15 of the time you'll be training. If you think you'll be too poor to train with Genesis for some reason, then I'd raise Big Bang. Genesis is generally raised until you can 2hko Skeles, which greatly depends on your equips.

^ btw Reset doesn't cancel the ele wand boost.
