@illuminye: Some time when Cygnus Knights were first released, and before their big revamp that changed their level cap from 120 to 200 (like before 2014?), there was this quest you could do on level 120 Cygnus Knight characters that let's you create an Adventurer that starts at level 50 with a Cygnus Knight skill and their little summon thing. Mihile's Soul Driver for warriors, Oz's Flame Gear for mages, Irena's Wind Pierce for bowmen, Eckhart's Vampire for thieves, and Hawkeye's Shark Wave for pirates. They were better than the other skills Adventurers used to have back then and also improved training speed a bit. But there were a couple negatives of creating an Ultimate Adventurer, missing HP and MP because skipped 1st job advancement bonuses, and inventory slot issue.
One thing that was cool about Ultimate Paladin was, you could use elemental charges with Soul Driver, this was when Paladin's elemental charges were buffs before being changed into actual elemental attacks. Ice Driver was literally cool, but nexon had to go and frick everything up!
Oz's Flame Gear is an extra DoT, probably useful for F/P Arch Mage.
Eckhart's Vampire is like a healing + knock back(does it still knock back?) skill, like a fusion of Assassin's old Drain and Gust Charm.
Hawkeye's Shark Wave just had good range. It's like a mini Bucc Blast.
I don't know what to say about Irena's Wind Pierce, it's just slow. I'm pretty sure Wind Archer's Wind Pierce had healing properties, but not Irena's, which was a letdown.
my F/P is a UA I'm not sure how effective is using flame gears for stacking DoTs for mist eruption (since it has a slow cast time and low duration), but I like how it pushes my character to a fire themed side. As for the summon, I use it out of habit, gets crowded.
Too bad I don't like F/P though, I only leveled it to 170ish because she's cute.
@deeemon I did the UA quest on my pally for max soul driver, it was SO good for Chaos PvP and KS wars at galloperas. Slipstream just made both easier.
