FFXI Mob:Crawler  

Present Time

Before confronting a Crawler, you will want to be about level 4-9... just be careful if you're level 3,4,or 5. Don't take this thing lightly. It can poison you, which by the time it has enough TP for it, you will already be close to low HP, making it possibly fatal.

Crystal War Era

Much stronger than its future counterpart. These mobs are really easily linked so you will want to be vigilant if you are of lower level.
