For multiplayer, I was a big fan of a nice high damage Lancer Staff that I had made, then I tried out a Babel Club with +4 petrification on it that I had won in a roulette on a whim and had a hard time playing together mode without it after that. Had fallen in love with its far-flying charge shots and the damage that it did in combination with Energy Charge Lv. 4. Very common to one-shot people right out of the gate.
Only recently have I replaced my Babel Club for Together Mode, and that is with a Magnus Club I got ahold of from solo play that has +4 Dash ch. shot and +3 In-peril autododge. The very short distance that the charge shot travels is a bit of a handicap, but unbuffed it hits for 259 from ~16 yards - double that if you're fully charged from the Energy Charge power. But I've stopped using the Energy Charge since the base damage is well-enough as it is to take care of most opponents, instead opting for Transparency Lv. 4 and Jump Glide to both get me up close to people before they start dodge-spamming at the sight of somebody wielding a club coming at them. These powers also work well as a quick oh-shit button in combination with Brief Invulnerability since you have to be in close proximity to get good use out of the weapon.
All-in-all, I've come in first for Free-For-All 31 times out of 34 ever since making the swap to the Magnus, and average between 9 and 14 kills per match. Highest match score so far with this was 3750ish
So I've been fusing arsenals upon arsenals of weapons in search of the perfect Magnus club to replace this one. The requirements I'm trying to shoot for in terms of the stats that stick are that it have Dash ch. shot modifier (no less than +3, but am hopeful of making it up to +4) as well as having
any amount of Shot range increase. So far after dozens upon dozens of fusions of weapons that have these stats in order to get pairs of things that compatibly combine into a Magnus Club that have any of those mentioned stats on them, I have yet to be successful in having the Shot Range modifier light up when showing what will apply while fusing. So either I've go terrible luck, or I missing a key function of how stats transfer while fusing, or the Magnus club is programmed to not be able to receive a Shot Range modifier. Beginning to think that it might be unable to have Shot Range on it, but I will press on experimenting to attain my perfect little killing machine.
As for solo, clubs are pretty hard to play with on the Land Battle portions of levels (hilariously easy for Air battle - you just hold down continuous fire and all shots are deflected - which is
nice because I'm now attempting to beat all levels on difficulty 9, and the air battles are where I die 80% of the time...) so I tend to stick with blades that have a steady damage output or things with strong homing. Currently it's a decent Sonic Cannon that I've been moving out with. Good homing, nice strong charged attacks, and range that isn't laughably low. It got me in trouble the last time I played the Palutena's Temple level on 9 difficulty. Had reached the boss fight without dying and was doing well in the fight, but the homing on it ended up killing Palutena while I was trying to aim at the Chaos Kin so I ended up finishing at 8
The jury's still out though, for my preferred Solo play weapon. The entire first playthrough was done with a lancer staff, but I quickly grew tired of it after trying out other weapon types. Still can't find anything that I'm truly happy with.
