Thanks Rudy!

What does each floor offer? are there are more mobs? boss? 

There are no bosses in Giran Prison. Normal mobs like bandits, evil spirits and undead spawn here. One of the best places to get EXP, but the mobs only drop adena and it's a pretty boring hunting spot IMO.

Be careful this place is the nr.1 spot for PvP. Be sure to have enough pots and escape scrolls. And it's also recommended to random teleport frequently to avoid PvP ganks.

 

Floor 1: Good for lower levels and people who don't want to get swamped by mobs. At least level 45 (but I recommend level 50+).

Floor 2: Great for mages and int elves.

Floor 3: If you're at least level 52 it can be a nice floor to level, because it's not as populated with players as the other floors.

Floor 4: A lot of mobs, you'll get swamped quickly. I would only go here when level 55+ with good gear.

f1 and f3 if ur single target

f2 and f4 if u can aoe

f4 is harder because of archer mobs (f3 also has archers)

f4 best floor if no1 else is hunting there.

always complete (or try to) 3h GP time if u want to lvl fastest way possible.
