got 300fg to buy items for, or boost whatever really.

im level 30 or so summoner, but doesn't seem to be the most fun class to play

So any hint what the most fun char is to play?
and items for that

monk is the most fun to play for me

for 300fg i can get you level 83/90 armor set + a weapon

all classes are fun depending on how u play them imo, except jester which is a little kinky :S

you'll eventually want to level up most of the classes to make your builds "optimal" so just start with one u have more initial interest in and have fun cause you'll want to just power level the rest

like what aurealis said 300fg (give or take) should get you pretty much a good set for 1-2 characters depending on their quality

tip: when u get a "cube" item from achievements, think about how u want to spend it, don't do anything to it yet cause the cube by itself is worth a bit in game as well.

Need builderset (cheap one so I can start with the farms myself)
and perhaps a level 80 boost or something?

The dungeon defenders wiki is really useful for general info.

Personally, I find monk a fun class.

Tower Monks are usually appreciated for some of their aura's and hero/TOWER boost really makes you liked by even players who don't really need your aura and have a build of their own, b/c tower boost will repair / up the damage their own defenses do and by proxy make things speedier and less likely to fall apart.
