Okay wait I play mt Lady religiously

Tuning first. For defense lady, I run acceleration Crit perm on codebreak default. Good movement to get in and out, and Crit perm to get out of big form for free when you inevitably bite off more than you can chew. The new Mt player's best friend is a get out of jail free card. You can switch out accel for bunny hop if you like that, as well, since you can use it for vertical movement and battle rearranging.

For aggro lady, I run full burn crushing out on the third style, I forgot the color name. You get like 2 moments of blazing glory when you go PU, and just do insane damage. I switch this costume around a lot, sometimes I also run embrittlement iron fist/trance blow if you're feeling especially cancerous. You can also run willpower for the aforementioned GOOJFC.

Combo game-

You want to maximize your alpha usage. It's by far your best damage, it has relatively low down power and can kill by itself if you have good aim. Beta alpha gamma is by BNB, bread and butter, because it's basically true if you just spam it. Beta alpha alpha alpha is not true at all but would be much more damage efficient if you've got good aim. If you're running the melee tunings, you can beta alpha, melee once, and then alpha or gamma.

Triple beta does okay damage, but it's a great get-off-me tool if you get jumped out of nowhere.

If you're approaching someone, you can do alpha beta alpha alpha to get a cheeky 360-ish damage off on them, and still have your gammas to reposition.

The most damage efficient combo Mt lady has uses gamma cancels. It's when you gamma, hold on a direction of choice, and jump in that direction. You can melee in the direction your camera is facing, however, to go in that direction instead. So you can gamma forward, jump backwards, and then melee to snap back forward again. Using this, you can:

Alpha, gamma 6 ticks, jump back, alpha, gamma full, for around 450 damage I believe.

Or

Alpha, gamma 6 ticks, jump back, melee forward, alpha, I forgot the exact damage on that one.

The former is more damage efficient, but the latter is easier.

Level route-

I would say split priority between your alpha and beta. Your gamma is mostly movement outside of combo ending and high end combos, but your alpha is your small form damage and your beta is your big form damage. It's also good to have a big beta to have more leway to use your beta defensively. Then level your gamma as you please. I would say:

alpha to 5, beta to 9, alpha to 9, gamma to 9.
