Just like how the archer queens ability makes her invincible and forces opposing defences on other troops, we have a spell that is short radius and starting from 1 second, makes troops in range of the spell invincible and distracts defences to less important troops. Second spell is a hold and swipe, which directs your troops to defences you wish to attack first while the spell is still valid when applied. Swipe ranges with level from 0.5-2 units (1square-6squares)
