"Broken" twink items

[Daldaen]

SoW potions on any character after level 20. Just drop 200 play have 10 hours of SoW available. Any time you need it. For someone with many Alts this is key.

Fungi is the biggest one that you excluded. Everything else is sort of meh.

Fungi Staff as Ele mentions is basically the same as Fungi. Together they are even more ridiculous. Also the Dragon Teeth are ridiculous. But very few people have access to these.

Necro/SK - CoS
Druid/Ench - Goblin Gazughi Ring
Wizard - Flux Staff
Magician - Pet Focii
Bard - McVaxius Horn (speeds up AE kites a ton)

Necro/SK instant Invis is ridiculous. Druid/Ench can charm kill so much easier with Gazughi Ring. Wizard Flux Staff makes grabbing quads post 20 much more fluid. Magician pet Focii change the power of pets from 4-50. Bard Horn is the only thing that increases your speed in killing AE trains really.

Melee nothing is worth mentioning outside of Fungi/Haste/Good weapons.
