Um giants are already OP, TRUE the damage reduction makes them not as powerful as they used to be, but giving them area attack is like giving the medusa an area petrify ability.
Here's my ability ideas:
Juggerknight
The axeman, they do a little more damage with their axes. passive ability with a cost of 200 gold and 200 mana with a waiting time of 30.
Spearton
Extra plating, they have much stronger armor, reducing the damage they take. PASSIVE 400 gold and 50 mana with a waiting time of 30.
Crawler
Cobras venom, the crawlers now inflict poison. PASSIVE 300 gold with 300 mana with a waiting time of 20.
Bomber
Sprinting training, they are now much much faster, can catch up to a shadowrath now, PASSIVE 500 gold with a waiting time of 60.
Bigger bombs, increases the bomb radius without increasing the damage, PASSIVE 300 gold with a waiting time of 60.
Shadowrath
Shinobi level 3, increases foot speed when in shinobi, makes it so you can catch up with a miner with miner hustle when upgraded. PASSIVE TO THE SHINOBI ABILITY 600 gold and 250 mana with a waiting time of 30.
Archidon
Scout, the archidons vision increases along with its range, it can shoot further and see the entire map (so if your on grassy hills and your archidon is back at base and has scout, activate it to see the entire map all the way to your enemies base), ACTIVATE ABLE ABILITY that costs 350 gold and 50 mana with a waiting time of 40 to research, 50 gold to activate.
