Super Secret Sleuth template:
120 Mysticism
100 Focus (Crystalline Ring to 120)
120 Spellweaving
110 Ninjitsu
100 Hiding
90 Stealth (Cloak of Silence + Shadow Dancer when needed)
80 Magery (Crystalline Ring to 100)
High powered offense with Rising Colossus + Word of Death. High defense with Smoke Bombs, stealth, Spellweaving & Mysticism spells. Being able to smoke Bomb, stealth away to create distance and cast another RC really makes the template.
There's not much this template can't take down. I think I've put it up against Grizzle one time and had issues with being able to cast RC on the tiles. I've solo'd Travesty with that template however it took over an hour. Overall I don't think I cast but 2-3 Magery spells anymore on most my templates: Recall, invisibility and resurrection.
This is the template I strive for on every account on every shard I play coupled with Soulstones of music skills for auxiliary support depending on the boss.
