Another thing i encountered in TDS, still with the Archer Tower, is Death Mark. This... is a tier V upgrade which increase the tower's damage for each enemy killed. However... There is no point getting this upgrade who "grow stronger over time" if you get it on last tide. Only use for the moment of this upgrade would be if there is an endless mode... The fact that you get it on the late game is sad because this could be a tower that make you progress from early, to mid, to late game peacefully. + Damage buff per kill is mid when this upgrade can get like, 5 kills and then the game end.
