Classic towers

Classic upgrades by stage

Classic Rush adds the classic upgrades stage by stage, five for each tower type: none on stages 1-2, and each new level from the stage in the first column on. The tower pages give each tower's numbers before and after.

From stage	Marksman	Barrack	Mage	Artillery
3	Selling after wave 1 returns 90% (was 60%)	Soldier health x1.1	Range x1.08	Damage x1.1
5	Range x1.1	Soldier armor +10 points	Each hit lowers armor by 3 points for good	Range x1.1
8	Hits count armor 10 points lower	Respawn x0.8, rally range x1.2	Prices x0.9	Prices x0.9
11	Range x1.1 again	Soldier health up again (+20% over the base)	Damage x1.15	Big Bertha and Tesla X104 ability prices x0.75
16	10% chance of double damage	The enemy a soldier fights takes 10% of each hit the soldier takes	Each hit halves speed for 0.5 seconds	Bombs deal full damage across the blast (the Musketeer's Shrapnel Shot too); Tesla chain jumps deal full damage

The Barrack upgrade from stage 16 also covers the Sorcerer Mage's elemental, the reinforcements and every hero except Drakkan and Ashbite; Prince Denas (stage 18) does not get it. On stage 1, Classic Rush locks Marksman Tower, Adept Tower, Footmen Barracks and Dwarven Artillery, so only level I towers are built there.
