Ok so a lot of my friends play Sylestia and a lot of them have been struggling with the event mobs (the bandit raids and now these mushroom guys) being incredibly difficult to defeat. If you are struggling with this I thought this may be helpful.

1) Use a team of lower level Sylestia.

The mobs adjust to your party level so if you are using a full group of 25s the mobs you get will be 20-25. If you are using a group of 50s the mobs will be 47-50.

Why?

Because level 50 mobs, due to the mechanics of any game like this, assume you are using level 50 gear. Since we have only really had access to level 25 gear you are REALLY hurting yourself trying to go up against these guys. Further, a level 50 boss is going to assume that you not only have level 50 gear but GOOD level 50 gear (purples and the like) and thus will completely OWN your high level party.

Since we have been locked in zone 1 for quite a stretch it is likely to assume that you have some pretty frickin SICK level 25 gear. I myself have a number of mythical pieces and what isn't red is absolutely orange or purple. I'm geared to the teeth on a level 25. So my level 25 team just STEAM ROLLED all of those 3 and 4 star mushrooms of the appropriate level and killed the boss with minimal potions use. This is the BIGGEST and most important piece of advice I can give you. Lower level party.

If you don't have a ton of awesome level 25 gear go with an even LOWER level part (15ish) and use the items from town. Those bracelets are sick on a level 25 let alone on a level 10. You'll do just beautifully with that gear.

2) Make sure your party are all around the same level.

On a second note to party level, make sure you are about even with yourself. A level 38, a level 25 and a level 20 are really going to struggle because the level 38 is going to drag the encounter up by a lot, making your other 2 pretty well useless. Also again with the level 38, the mobs will now think you have better gear than you have and will do more damage. You don't want this. So keep them within a 2-3 level spread.

3) When the event hits 90% of mobs killed before the boss fight, go get healed in town. Pretty obvious, but will save you on elixirs in the main battle. Use potions if you are really hurting after a battle to keep you going instead of going to town. They are cheaper.

4) When the event hits 80% of the mobs killed save up your mana for the boss fight. Starting a boss fight at 100 mana and hitting him with 3 finishers from the gate is incredibly helpful.

Very good advice! Especially #1
