Y'all do realize for a true new EQ player a lot of those descriptions are going to mean nothing, right?
I'll try to enlighten on a few of the more unique terms to the best of my ability:
HT -
Harm Touch, a Shadow Knight ability that deals a massive amount of damage on an extremely long cooldown.
mem blur -
Memory Blur, clears aggro from a mob
tash -
Tashan line of spells (lowers a mob's resistance to magic)
twitch -
Covetous Subversion, transfers mana from the Necro to another player.
coth -
Call of the Hero, summons another player to your location.
mod rod - Magicians can summon
Modulating Rods and give them out to others. They allow anyone to instantly to convert HP to mana.
And as a casual player on and off for many years (no raiding or level 60s as I have an alt addiction) I don't even know what "train up" means in this sense.
