Excellent guide. Perhaps worth noting that one variety of 4* troops also buffs critical hits.

An eye-opening part of your guide was the linkage between the guardians and the big one-shot heroes. This makes me more confirmed to do more summons this event to get the Jackal to complement my Joon!

It may go without saying in a Titan guide, but it’s probably worth noting that dropping 3 gems on the titan’s weak spot stuns it. There’s no more effective way of avoiding damage to your team! I also always have antidotes going into a Titan fight if it has any debuff; removing these is essential to a successful attack.
