"Interesting" would be the ideal. Less of things like K64's Burning/Ice combo and more like the Bomb/Cutter. We don't any "look how dumb this ability is, lullz", especially if you plan on doing more than one.
No doubles is gonna remain no doubles. Arguably, one should be able to pull out a different ability to get the desired effect. For example, Cutter/Sword for a big scimitar, Hammer/Stone for a mighty maul, ... uh, Archer or Crash Missile/Bomb for a missile array? Certainly not Archer -- that'd be stupid.
Well, the Dark Matter Trilogy had bad combinations for abilities, such as Kine + (insert anything) and some of the 64 mixes, but they also were single functions. Remember the opener to this I.F.? How it was about expanding upon things? Usually, effort isn't wasted on garbage. (Unless extremely comical, like Mints' Ouch Ability Review, which I apparently can't make a link to :/)
Ugh. For the last time, I can't. I have no ability to do that (for some reason). I checked. I went in, I looked about, I even gave myself someone else's pseudo-permissions. Then it showed up, but I couldn't do anything about it with the mock-view.
No? They are supposed to have influence of the two abilities, not necessarily a "theme" of one or the other. For example, in my ... example of Jewel, it was highly defensive, partially stationary, and bounced back attacks. Fuuusion.
Aaand I just found out that I didn't have the form sending in which abilities were mixed. Well, that's gonna be fun...
That's a pricklier pickle (prickly pickler?) than it seems to be. Between modifying the whole image -- of which no source graphics are possessed leading to compression -- and matching the exact font on the font overlay, it's a beyond my knowings of how to match it. Furthermore, I think all but two of the "current" features ain't really current.
That wonky automated indexer never seems to do stuff right. It's supposed to move the prior thing to the "out of season" list when finished, but... it never seems to happen. Given the length of time between doing this, I never remember how to force the transition, possibly by making the next one? This is why I don't like things that I didn't code (or people I don't have under mind control).
