Establishing rules and mechanics.

So with four members in our group, we decided that our game would be a 2v2 strategy game. The aim would be to eliminate the opposing team.
My character is the slender-assassin type, so naturally it would be a melee dps. Same with Conor's character.
Jacks character had a shotgun, and Daniels character had a crossbow, this worked out perfectly because both teams would have a melee and a ranged dps.

We started to elaborate on the skills we would have for each character and decided as balanced as the game would be with the teams with one of each spec. we would further need a additional speciality to make the game have an actual element of skill and strategy rather than the all out battle it would be with all four characters being damage dealers.
So we added a utility speciality to each of the characters. This speciality would include abilities that had a 'utility' as the name suggests, with much less damage dealt. This included things like cripples and blinds.

 There would need to be a skill that could be used on every single turn, this would be the basic attack, or the basic utility/disable spell. We also needed more abilities that would be more powerful, and because they're more powerful they would need to be limited. We decided that they would have round-based cooldowns to act as that limit for the abilities. They're four turns in one round. The second ability would have a 3 round cooldown which amounts to 12 turns, and the third ability would have a 5 round cooldown which would amount to 20 turns in total.

The third ability would be the 'ultimate' skill and we want it to be used strategically rather than using it straight away so it comes off cooldown ready for the next 5 rounds. We thought of adding a RNG element to the third skills, so there would be a set amount of damage and then an additional effect thats based on a dice roll or some other randomiser.

We did want some kind of 'one-shot' ability that would have an extremely low chance, and have something bad happen to you if you do not get that chance, but we didn't use that in the end.
