So, I've made a final decision. I'm going to stay working on this project. I still need artists and sound guys, but that is neither here nor there. All in due time.
In the meantime, have an update on heroes and some tentative abilities:
20% Coolor - +20% buff to attack speed in units in X radius.
Dash - Rainbow charges forward X meters, dealing Y damage to units caught in her path.
Filly Flash - Rainbow releases a burst of color, blinding all units in X range. Blinded units have reduced accuracy and damage.
Sonic Rainboom - Rainbow dash charges forward X meters, dealing Y damage to all units in the path, then releases a massive explosion dealing Z damage to all units in Y range.
Angel Bunny - Summons a permanent bunny to assist Fluttershy.
Kindness - Inspires a unit with confidence, boosting attack damage by X% (autocast ability)
Gentle Eyes - Units can't bear to follow through with their attacks, reducing damage taken by Flutteryshy by X%.
The Stare - Fluttershy gives "the stare" and all units that are looking at her are petrified for X seconds. Petrified units cannot perform any orders.
Gem-Studded Fabrics - Reduces damage taken by X.
Fashionista - Improves the armor rating of nearby units by X.
Gem Volley - Throws a handfuls of gems everywhere, dealing X damage to everypony within Y distance from Rarity.
Oh, It's On - Rarity goes into a beserker rage, preventing her from casting spells, increasing damage and health by X%, and reducing damage taken by Y%. (Flavor Text: "What in Celestia's name have you done?")
Twilight Sparkle -
Unicorn Bolt - Twilight hits the enemy with a bolt of magic for X points of damage.
Teleport - Twilight teleports to a point within X distance instantly.
Study - Twilight carefully observes her targets before striking, increasing her chance of dealing a critical hit by X%.
Ultima - Releases a massive burst of magic, dealing X damage to anypony near Twilight. (Flavor Text: "What do you mean this isn't Equestria canon?")
Buck - Turns around and kicks pretty darn hard, hitting a unit for X damage.
Farmer's Endurance - Increase movement speed by X% and life by Y%.
Apples! - Heals a friendly unit for X points of life. (Autocast)
Zap Apple - Summons a zap apple tree with electrocutes nearby enemies with electricity.
Defy Physics - Leaps up into the air and slams down onto an enemy unit for X damage.
Happiness Aura - Increases life regeneration by X% and attack speed by Y%.
Cheer - Cheers on an allied unit, increasing their damage by X%. (autocast)
Party Cannon - Fires her infamous party cannon at an enemy, hitting all units nearby and in the firing path for X damage.
I have yet to figure out hero abilities for changeling heroes Discord and Chrysalis. They will come next. Right now, while I'm working on my pathing algorithm, I'm solidifying game design details. Feel free to give input / suggestions.
