Grim the Overseer

Overview
 is the boss of Transylvania.

Strategy
To efficiently defeat this boss, a minimum of 6 players is recommended, Similar to the strategy involved to defeat Mortis The Flaming Sear, firstly lure the Undead Servants far from the boss spawn, so they won't get in your party's way when fighting the boss itself, You should also utilize the idea of Switching, Following the recommended 6 player raid party size, you must send out 3 players to initially fighting the boss, when those 3 players are low on HP, they shall switch with the 3 players not fighting the boss, That shall give time for them to recover their Stamina and HP, When the 3 players that are now fighting the boss are Low, repeat the process.
