First of all: Weapons are created by combining a sealed weapon and four different core types in Arcane Transmutor. Recipes are listed below; Cores can be found in:
HoDL HM - Weak, Tikal - Temple, Inferno - Fire, Gorge - Ice, RoFL HM - Earth.
Light Weapons
1-H Sword "Short Sword of Balton" (1 Temple, 1 Fire, 1 Ice, 1 Earth)
Knight-Tank weapon, Scout stat stick.
1-H Axe "Jungle Chopper" (1 Weak, 1 Temple, 1 Ice, 1 Earth)
M/W Buff gear.
1-H Hammer "Glimmer" (1 Weak, 1 Fire, 2 Ice, 1 Earth)
Champ-Tank, K/M, and for anyone who wants to play Ch/R with 1H + Dagger.
Dagger "Edge of Eternity" (1 Temple, 2 Fire, 2 Ice, 1 Earth)
Obviously: Rogue.
Heavy Weapons
2-H Sword "Justice Sword of the Jungle" (1 Weak, 1 Fire, 1 Ice, 1 Earth)
Warden weapon. More DPS and better attack speed than Axe while having 252 instead of 242 max weapon skill.
2-H Axe "Earth Seeker" (2 Weak, 2 Temple, 1 Fire, 1 Earth)
Seriously, don't use this.
2-H Hammer "The Trauma" (1 Temple, 2 Fire, 1 Ice, 2 Earth)
THE weapon. Over 15% more DPS than Gorge while lowering attack time from 4.0 to 3.5. BIS for Champion and pDPS-Warriors.
Ranged Weapons
Bow "Death's Kiss" (1 Temple, 1 Fire, 2 Ice, 2 Earth)
Scout weapon.
XBow "Hell's Whistle" (1 Weak, 1 Temple, 1 Ice, 2 Earth)
Stat stick for any Scout secondary.
Magical Weapons
1-H Mage "Wand of Eternal Fire" (1 Weak, 2 Fire, 1 Ice, 2 Earth)
Unfortunately 0.1 slower than Gorge.
2-H Mage "Netherlight" (1 Temple, 1 Fire, 1 Ice, 2 Earth)
3.6 attack time instead of 4.0. Wd/D ftw!
1-H Heal "Wand of Krishna" (1 Weak, 1 Temple, 1 Fire, 1 Earth)
Nothing to say here.
2-H Heal "Staff of Siddartha" (1 Weak, 1 Temple, 1 Fire, 1 Ice)
There is still no reason to drop the defense a shield provides for this tiny increase in heal output.
