stuck at 26% with all upgrades? I'm already at 63% and only have around 1/4 of the upgrades except for cocheta's rifle which is maxed out. that's with all the lag, stupid sudden unresponsive controls, bugs and etc. you're probably just doing something wrong with your game or just bad at it.
Survival mode is the third campaign, Fall of Telunos. Easy to do once you figure out which team compo you find most effective. Just make sure you have someone who can revive and someone who can keep the hp up on your team.
If you're having problems with amazons, just build a bunch of ballista towers. Enough of those make the amazons pop their enchant from a safe distance especially when upped to balista dens. Divers weren't a problem for me since I spammed temple of infernos near and around waters. Those + the ballistas mowed them down even if they can't be targeted. Don't rely on the undead towers anymore... for some reason they suck in this second game. Used to love them in the first. Have to agree that it's a terrible experience trying to defeat the bosses when it lags like hell.
Huh, what a weird hard badge. Levels 19-21 were easier than 16-18 because they don't have as much tower-blocking runes which make your towers more susceptible to valkyrie waves.
Anoint only increases normal attack damage if I remember it right. Used to always use it on my rogue since they have the biggest potential normal attack damage in the game.
