The unit with the highest possible damage boost is the Hillhome Huscarl - two upgrade paths for power. The five basic upgrades bring + 150%, then 30 - 30 - 75 either way.
Units that can do the Hydra grind on their own (with a decent hero) - Hamlar Augment, Tyrian Crossbow. Both will have over a 100 damage (HA: 149, TC: 120).
very nice game. Unfortunately, the AI is really a piece of cake.
Perhaps most useful unit: terran frigate - with the upgrade, shoots at nearly everything in a three radius.
The pulsar is fun: after you build it just crank them orbs, and you'll one-shot anybody. :)
brilliant on level 14 is a pain in the 4ss. The ninja boss is tougher than 5 pimped meteors. :/ The only hope is a double crit on a maxed out hunters den right at the start.
i think the Kongregate developers want to punish us for the few people that have been playing Kongai. :/ I'd like the card, but I'm not playing this stupid shit.
repetitive, easy, walkthrough is a bit mindless. Best glitch: Get stuck in an endless journey from the city you are in - into the city you are in. Reload, reap the riches.
interesting glitch: if you get +10 health on with necronomic tome, but your health is reduced to 0 with an attack the same speed, the increase does not apply. :(
to at last finish the never-ending discussion here: This is an example of a classic riff on the "super-hero" comic style, where women allways look good and have quite a lot on their chests. Its not a question of "morals", it´s a quesiton of aesthetics.
And they are quite beautiful, as I can assure those who are too afraid to look. ;)
