Trial 718

Defeat 400 plantoid-type experience yielding creatures with the Rageblow equipped.
After returning the Rageblow to the Magian Moogle you will be rewarded with the Goedendag.

If your going the solo route (or with a friend or two) like me then here are some monsters that meet the requirement:

Family	Name	Notes
Mandragoras	Mourioche	Monk type mobs, fairly annoying to solo but not impossible. Just goes slower than other monsters of choice. But there are groups here that do other trials that you can team up with and it can be faster this way. Not recommended to do alone though!
Mandragoras	Pachypodium	These are of course not something you solo. These are the Abyssea - Tahrongi Mandragoras which you can equip the club to do an easy 400. Kinda cheating but its legit.
Funguars	Brasscap	Fairly squishy monsters with low HP. If your solo or with a friend this can be very easy to do.
Goobbue	Any	These are never really grouped together so you'll never just do these. They are squishy though just they can hit very hard as well!
Flytraps	Puktrap	Really the only one available without level sync. in Caedarva Mire but aren't as low level as other options. But Flytraps tend to be grouped together. Unable to confirm for this specific group so its just a hypothesis
Morbols	Any	Hell...no. Never grouped together and aren't easy at all. There is a group in Abyssea - Konschtat called Morboling. There might be a group that rarely farms these for a Tiny Morbol Vine used to spawn Clingy Clare. Drops a 200k back and a key item used to spawn Eccentric Eve a very highly sought after NM. So its possible you'll find a group for these... just not likely. Besides wouldn't you rather do Mandragoras if your going the Abyssea route?
Rafflesia	Rafflesia	There is a level group 59-62 here in Fort Karugo-Narugo (S) but I haven't tested these though so no clue if they are squishy or easy or what.
Sabotenders	Spelunking Sabotender	Level 62-68...so the lower ones are ideal. There are groups that do these sometimes... just need to find them. Wouldn't recommend to solo these though.
Saplings	Treant Sapling	There are some in Meriphataud Mountains (S) level 56-59. VERY EASY and con Easy Prey to level 80. Hexa Strike takes 50%+ easy so this is a prime solo spot. Also in Abyssea - Konschtat there are Trotting Sapling.
Treants	Knotty Treant	These are in Grauberg (S) and aren't that hard but they do take time. Recommended to bring a friend to help do damage. Also in Abyssea - Konschtat there are Highland Treant.
