Ro Zeny has an unusual power to use, and we will be sent to good fighting. This is probably the second most dangerous part of the party. The puller must gather mobs for the party to kill without getting killed himself. In c4, skill damage can only be applied to 20 mobs at a time, so the puller must make sure to pull less than this. The puller often, but not always, will use hp healing potions, such as Healing Potions, Greater Healing potions, or in the direst of circumstances, Quick Healing Potions to stay alive. Pulling enough mobs that the party can kill them all, yet not getting killed on the way back, which is extremely important. Pullers need to take care to watch for mobs that disable in any way: a badly-timed slow, stun, sleeps, or paralyze from a mob will end can end pull in a heartbeat. When the puller then returns to the party, this is the most dangerous part of the pull. After the puller stops moving, the puller will receive a burst of damage from all the mobs catching up to them, and may die. Healers in the party should pay very close attention at this moment, and decide whether or not the puller needs heal or two to stay alive. Most of the time, they will be fine, because the tank will take over agro from this point on. Timing is critical at this point. The tank needs to quickly take the agro, or if the puller is the tank, build agro, so that the healers can start healing without getting attacked by the mobs in the train.
