Glaciate Tower: New Defense Building
Well, I think there could be a new defense tower, called Glaciate Tower. Believing there would be TH11 one day, this Glaciate tower will be prior for TH11 users, just as Inferno Towers are prior for the TH10s. This Glaciate Tower will be similar, but different with inferno tower. Inferno Tower shoots(?) fire to attack the opponent troops. However, this Glaciate Tower will freeze the opponent's attacking units (for a short while). This will be a splash damage type of tower. Every 10 seconds, it will shoot ice beams to all units within the 4 blocks range. It will freeze them for 3 seconds. After the units are unfrozen, they will have another 10 seconds, and then they will be frozen again. The weakness of this tower will be that it does not give direct damage (freezing won't kill the troops.) and a fairly low hp. It will only have hitpoints as low as Full upped Cannons... This tower will be very good to use together with inferno towers, where the glaciate tower freezes, and inferno tower burns them.
This could also lead to making a new spell, Ring of Fire. If you summon the Ring of Fire, it will exist there fore 45-50 seconds, and the troops within the ring will not get affected by the glaciate tower. However, you will not be able to use freeze spells while using fire spells. This will make users a lot harder to attack TH11s, but I am sure that there will be better units invented to fight TH11s too.
P.S, Glaciate Towers do not get affected by Freeze Spells.
