[Bishop] Which skill next?

Genesis, Angel Ray, Bahamut, and Maple Warrior in my opinion are the highest priority, with Gen and Maple Warrior being so important you should save points for them for immediately after you pass the book. Holy Shield is not that highly regarded, but I personally find it very useful in Zak and Horntail. The high lvl Bishops I know did not speak well of Mana Reflection, though I admit I did not ask them why they thought that. Big Bang to me seems so useless next to Gen that I have to wonder if it's just a trap for people that didn't find out about Ultimates after advancing.

Thanks for the input. My Genesis, Angel Ray, Resurrection, Maple Warrior, and Holy Shield has been maxed for a very long time now (thanks to DarkLily HT and Ascendancy HT <333) - I'm glad my choices were not that bad. I think Bahamut is useless since it doesn't help me with training that much which is why I'm putting points into it now (It's level 26 at the moment). Holy Shield is incredibly useful in my opinion. In Zakum, it frequently uses his Lightning/Sealing skill. In Horntail, it's useful in case your party members fall down and get weakened or something. In Grandpa, it's extremely useful since he seals you half the time.

Big Bang will add a little versatility to your array of attacks. It gives you a stronger non-elemental attack, so you're not stuck using claw or dooming holy immune monsters if you ever need to hunt any (like Guardians for gold boxes >_>). It also looks cool, and helps at APQ. =P

I have Mana Reflection maxed, and honestly, the damage is so insignificant, that it doesn't seem to ever matter. Plus it is contradicted by Energy Resistance. The most this skill has ever done for me is save like 4-5 ARs during a Pap solo.

And like Cyanne said, 30 points to save 3 Mana Bulls ever 10 minutes, is totally pointless. 1 point in infinity already accomplishes more than 1/4 of what the other 29 add, so leave it at that until the very end.

Thanks for your advices. I still believe Big Bang to be a very unnecessary skill. I never train with it, and my APQ's are just fine without me as an attacker (usually anyway). Not to mention, if I use Big Bang the moment I get bumped, it gets cancelled since I can't use the skill in the "air". I find this extremely annoying. When the Gachapon Chest event ends, I won't have a need to go to Crimson Guardians; not that I go there anyway.

I like Mana Reflection because it's a fun skill to have in my opinion. I put in 1 point in the skill a while ago since I wanted to see it in action. It's kind of amusing to see damage being reflected. Also, it's a long lasting buff and I love seeing lots of buffs on my screen =p.

As for Infinity, I agree with you and Cyanne. I believe nobody in MapleStory is so poor that they actually need Infinity. It may be useful for the Event Maps, but I never liked that event anyway - I wish it never existed.
