Even though this effect can be [[chain]]ed to, it cannot be [[chain]]ed to with an effect that [[negate]]s the [[activate|activation]] of a Spell Card, such as "[[Magic Jammer]]" or "[[Horus the Black Flame Dragon LV8]]" because the "[[Clock Tower Prison]]" card has already [[resolve]]d.

* The effect that stops [[Battle Damage]] is a [[Continuous Monster Effects|Continuous Effect]] that cannot be [[chain]]ed to.

* If "[[Clock Tower Prison]]" with 4 or more [[Clock Counter]]s is destroyed because a new [[Field Spell Cards|Field Spell Card]] is [[activate]]d, "[[Clock Tower Prison|Clock Tower Prison's]]" effect will [[activate]].

* If "[[Spell Canceller]]" is [[Summon]]ed or "[[Imperial Order]]" is [[activate]]d, all the [[Clock Counter]]s will be removed from "[[Clock Tower Prison]]".
