I'm making this post to discuss Tower ideas which will be added to Kingdom Rush: Legends (the TD version) later. Please judge them as if they were usable in any of the first three games ( KR1 / KRF / KRV ) as a third Level-IV upgrade choice, and compare them to their respective Level-IV Towers.
Grand Sage
Grand Sages are ancient wizards who wear an orange cloth across their body and wear a pendant of brown beads. Their brown hair is tied like upwards on their head, circled with the same brown beads. Their long beards match the tuft of hair at the back of their heads. With their offhand resting on a stick shaped like a slingshot and holding the same pendant of beads they wear, they wield simple brown staffs without any gem of power. Standing on a pedestal of gray stone with a glowing white rune and big, crude steps carved into the rock and vegetation on the top, they oversee the battlefield from the shade of two green trees of life. The Sage casts white bolts of holy fire which home in on and decimate their enemies.
The wise Sages of old punish enemies with holy fire and bring ancient lore to your advantage.
