My sage is finally lvl 50 and now has the 50 Yellow Hammer.
However I was fortunate to make it on it's first go, using only SK Bliss.
At the moment I have no resources and little money and wondering which hammer I should get for PvP. Currently using a Spotless, Crit-dmg (also has petrify) 45 blue on my other hand and although it's good, I would switch if something else is better.

PvP seems harder at 50 and still mulling over what stones I should get....

Also in terms of talents 4 come to mind, but I might be wrong:
- Magic Defender: Using normally because of good def and mdef
-King of the Jungle: Mage masherness
-Prophet: 2 handed serks go down
-Scholar of the Holy World: Hit rate vs sins, rangers

I really don't know which one to use at 50
(unlocked all talents and most are at lvl 2)

If you have the time/resources make a 2nd orange stun hammer. Yellow + Orange stun hammers will probably be your best melee build at that level.

1. Prime setup at 50 is the yellow pontiff's/orange archbishop dual setup. We didn't have prefixes back when I had a sage, but I'd recommend either dual accuracy or spotless. You have close to a 34% chance of a stun.

2. Best talent setup would be scholar of the holy world, the hit bonus can pretty much finish off most rangers, mongoose may be anti stun but it's not anti damage, you can still hit through it.

3. Full crit damage stones in your hammers are fine normally but I'd aim for a crit rate of at least 56.21 (that took way too much math ><)in wolf form to counter pvp sets.
