Magic should be:
To Hit: Attacker Int vs. Defender Wis
I think Dex (mentioned earlier) makes better sense, because of the essence mechanic. (and because Magic v. Def just makes my teeth hurt)
The current character stat 'Essence' should be called 'Wisdom'. Essence should instead be a global stat just like food, and be used differently - but that is a different discussion.
I disagree with this pretty strongly. I think "wisdom" needs to be removed from the character creation screen entirely, it is confusing and not mentioned anywhere else in the game. Explain it or toss it please.
Melee should be:
{...}
If the attack kills the squad member, the next squad-member rolls to defend as well, and receives the remaining damage (modified by his defense roll). For example:
I like your idea of combat mechanics up to here. I think on a single attack roll, it doesn't make sense to carry that damage on to the next soldier in a unit. Jimmy has 5 hp left, but his friend Jack has 10. Slavering beastie chomps on Jimmy for 15 damage, but it doesn't follow that the bite is so powerful it kills poor Jack, watching nearby. Jimmy is just pulp.
a lot of great brainstorming in here, nice thread. I'd add support for:
Break up multi-soldier defense in the same way attacks work now - multiple individual defense/attack rolls, with perhaps a small bonus based on the total number of soldiers in the squad.
Magic v. Def is just not okay. Magic v. Essence seems tricky, because of the currency-like essence system. Magic v. Dex seems like the best approach without the addition of a set if resistance stats. Elemental resistance stats! Elemental! Says it right there at the top of the screen.
Obviously in-game references/documentation needs to be worked out too (no clarity on per-soldier atk mechanic, what the eff is wisdom, etc), but I'm frankly more worried about the system getting some sophistication (units don't get decreased atk/def for losing members, no elemental resists - Look a fire giant! Hit it with a flame dart!).
