Basic Guide
The Quests
Required Level: 145
The quest line is actually relatively "simple".
All you have to do is accept the quest, and then fight 999 monsters.
Then, turn in the quest (which allows you to move to the next room), accept the next quest, and kill 999 different monsters.
Continue this pattern until you reach a mini boss room (the bosses shouldnt be very hard to handle).
Finally, you will reach a repeatable quest which you can complete to recieve a droppable item (like Papulatus) that allows you to summon Pink Bean once.
The Boss
Required Level: 180
Pink bean is the relatively small boss located near Leafre in the Temple of Time (ToT). Don't let his looks fool you though.
He has a total of TWENTY ONE HP bars, so be ready for a long fight.
Notices:
1. Pink Bean is one of the few bosses that is neutral to poison and lightning.
2. Pink Bean has statues that you must kill before moving on to him.
3. Pink Bean has damage reflect.
4. Pink Bean has extremely high defense, halving almost all damage done to him.
5. Pink Bean summons Mini Beans throughout the fight.

Tips:
1. Use an Auto Potter.
2. Set up the loot system beforehand (assuming your fighting with a party) so their are no false assumptions and looters after the fight.
There is no real guide on how to defeat Pink Bean himself, just the regular bossing criteria. If you're high enough level to fight him, you should know the drill.
