I have a lvl 24 mage equipped with this:

Angelic splintered staff

+6% Enhanced Effect
+53 Max Life
+1 to 2 Mana per Attack
+1% Life Steal

Mystical linen padded robe
Level Req: 5
Defense: 0 to 9

+149 Max Life
+1 Mana Regen
+1 to 8 Mana per Kill

Mystical lightning III

+1 to 5 Mana per Attack
+1 Jubilance

Mystical wild heal II

+60 Max Life
+123 Max Mana
+2% Life Steal

I have no fg and I am trying to gain some to build a character. Should I just reroll my character? I am not finding any good FG, I do not with to be healing people and don't think its even worth me healing. I have trouble killing monsters in arena, I have 0 proficiency in everything.

I wouldn't recommend re-rolling, but maybe try creating a new character like a fighter.

If I create a fighter, what should I be putting points into, or recommend me a guide I can take a look at.

For Melee-


When your at lvl 55 with your gear on you want your dex to be around 110-120. Put the rest of the stats into strength
For items-

Weapon- Enhanced Effect( the higher the better)
Armor- For catacombs look for heavy armors with EE. For arena look for heavy armors with stats such as strength or dex
For charms- Look for stats such as strength or dex

What is the difference between an axe and battleaxe? And sword and Longsword? Can a fighter use both?

A battleaxe and longsword are heavy weapons and attack 2x slower. Fighters can use Swords, Clubs, Axes, Longswords, Spears, Polearms.
