Well, I am start to think about this recently, the idea is come from the
ClashRoyale.
Unit Name:
Fire ElementCost:
300Status: ATK 40(M) DEF 10 MDF 15
Ability:
*This unit can attack the place without enemy unit. ( This is the most important part, which will relate to ability. )
*After this unit attack, the terrain (Important!!!) been attack will been " Burn " for a period of time. ( As long as Tomb will exist )
*Take 125% damage when facing Water Unit. ( Ice Element, Water Element...etc )
Field Effect:
Burn*The water terrain can't be Burn.
*Any unit in the Burn field will lose 10 HP, at the beginning of turn.
*Fire Element will restore 10 HP in Burn terrain at your beginning of turn.
*Any Water Unit get into Burn terrain will disable the Burn effect immediately and lose 10HP.
Basically this idea is to involve a tactical thinking about “ Control Field “ Means you can force enemy take more damage to attack some direction you don't wish to. Well, Just a first thought, but might be interesting. Need some further discussion.
