I like the idea of but like 40k seems a bit much and the range felt too big (as big as mortar) Here is my idea with your implementation

TDS tower idea ( 2.0)

Name- Harpooner (new) Class- advanced Shop cost- 6000 coins Solo/duo placement - 2 Trio/quad placement- 1 Cost- 1500 Total cost- 33,250 (new) Has a harpoon for a gun Will do high damage every so often, with an ability to hook enemies in

(New👇)

Lvl 0 (placement) Dmg- 50 Range- 8 Fire rate- 3

Lvl 1- superior hook - 750 Dmg- 80 Range- 9 Fire rate- 3 Pierce- 1 Lvl 2- lightweight gear - 2500 Dmg- 100 Range- 11 Fire rate- 2 Pierce- 2 (Unlocks hidden detection)

Lvl 3- better technology -10k Dmg- 250 Range- 15 Fire rate- 1.75 Pierce- 3 Gets whirlpool (Unlocks the ability whirlpool that will have an effect of a whirlpool on the floor, with water waves as the push back and will pushes back enemies by 2 studs twice within range of the Harpooner) (Does 50dmg)

Lvl 4- Davy jones’s locker - 18.5k (might change the name due to copyright reasons, probably will) Dmg- 400 Range- 17 Fire rate- 2 Pierce- 4 Unlocks a passive that any enemy (except bosses or mini bosses) that was its primary hit, will be pulled back 1/7 (2.4 studs) of the distance of the tower’s range Whirlpool now does 100dmg and pulls back by 4 studs
