Basically this ^^. King Shynee has a bigger damage boost and is on 15 to 10 turn CD. 25 Turns is brutal and I'm not going to grind that down to 15, that dungeon was tough. I would rather use her but 25 turns is really hard to stall on most of the newer descended dungeons.
I might make getting her down to 15 a long term goal but with the rarity of the dungeon, the difficulty of farming and the brutal nature of skillups in this game I'll take a pass.
King Shynee is 17 - 12 turns but otherwise I agree. I rolled Sun Quan in the recent godfest and he has 2x healer atk + 2 turn delay starting at 18 turns. I will use him instead of Sandalphon even though he is Water not Light. I hope his eventual ultimate gets a light sub color.
