Archer Skill Master list
All the skills presented here are subject to tweaking once implemented
Called Shot: instead of attacking, the Archer can choose to take an overwatch stance, automatically attacking the first enemy to get in range the next enemy phase. Works with ballistas.
* Reaction Shot (active skill): Activate this skill instead of making an attack this round. During the next Enemy Phase, any time an enemy moves into any panel within your attack range, make an attack against him with -15 to hit. You may not target any target more than once per turn with this skill, and you may not double-attack regardless of your relative Attack Skill.
* Nothin' to do but Dodge (passive skill): When attacked by an enemy who is not inside your counterattack range, you gain +20 to Evasion.
* Point-Blank Shot (passive skill): You may use bows at a range of 1, but with a penalty of 1 Damage and 15 Accuracy.
* Sniper's Nest (passive skill): Double the defensive benefits of terrain you are standing on.
* Prognostication (passive skill): You keep your eyes on the horizon, and when someone charges you, you have time to anticipate. If an enemy moves three spaces or more to attack you, you gain +20 Evasion against them for that round.
* Premeditation (active skill): You may activate this skill once per battle. Reduce your MAG to 0, and receive an increase to SPD equal to half the MAG lost. On every subsequent turn, your MAG increases by 1 up to its normal amount, and your SPD decreases by 1 down to its normal amount.
Arc shot: On their turn, an archer may choose to extend their range by 1 tile in exchange for -20 to hit on the attack.
Careful Shot: Some form of exchanging damage for extra hit
Flush Shot: After attacking an enemy on defensive terrain, the target loses terrain bonuses until they complete one combat.
Sighted in: If the unit with this skill attacks a unit they attacked the previous round, +15 hit and +1 DAM
Lucky arrow: Once per map, an archer may add +30 to hit for one attack
Steady Aim: If the archer uses no move this turn, +? hit and +? Damage
I think this is all of them.
