""WOW - BT"" Gurtogg Bloodboil

Phase Switch. Gurtogg Bloodboil starts in phase 1. The Phase Switch is commanded by the use of the Fel Rage Reaction. The phases will change the ability that Gurtogg BloodBoil and his lair does.

When switching into phase 2, Gurtogg Bloodboil will reach at any costs the Fel Rage target. The phase will last 2 round.
When switching into phase 1, Gurtogg Bloodboil will return to the previously attacked target (before switching into phase 2). This phase will last until 2 Bloodboil Lair actions are used.

Legendary Resistance (3/Day). If Gurtogg Bloodboil fails a saving throw, it can choose to succeed instead.

Ready to Fight. Gurtogg Bloodboil has advantage on initiative rolls.

When under Fel Enrage (see Fel Rage Reaction) the attacks become four.

General

Arcing Smash. Melee Weapon Attack: +11 to hit, multiple target, 5ft reach. Hit: Gurtogg Bloodboil, attacks cleave the targets in a cone in front of him doing 17 (3d8+5) slashing damage to all of them. This action cannot be used in the next turn.

Phase 1

Acidic Wound: Melee Weapon Attack: +11 to hit, 5 ft reach, single target. Hit: Gurtogg Bloodboil, attack a target doing 20 (3d10+5) acid damage. In the case of an hit, the target must also do a DC 16 Dexterity saving throw, getting -4 AC and being poisoned by 12 (3d8) posion damage for five turns (damage applies at the end of the player's turn) on a failed save, or evading the altered conditions on a successful one.

Phase 2

Fel Arcing Smash. Melee Weapon Attack: Replaces the general action Arcing Smash. +11 to hit, multiple target, 5ft reach, 15ft range cone area. Hit: Gurtogg Bloodboil, attacks cleave the targets in a cone in front of him centered on the target that has the Fel Rage debuff, doing 20 (3d10+5) slashing damage to all of them. Also the targets will have the heals received halved for 1 turn (ends on Gurtogg Bloodboil next turn).

Dash. Gurtogg Bloodboil can perform the Dash action as a bonus action.

Fel Rage: as soon as the Gurtogg Bloodboil's Lair casts the second Bloodboil, Gurtogg Bloodboil will enrage changing the behaviour of some of his actions due to the Veil that erupts violently from his body. It chooses a target randomly (160ft range). That target and Gurtogg Bloodboil gains the Fel Rage buff forcing Gurtogg Bloodboil to run towards it. This buff ends at the end of Gurtogg Bloodboil's second turn and for its duration will alter the target giving:

• +100 maximum HP (recovering the difference, i.e. 60/80-->160/180)
• +4 AC
• all direct damage roll attack done by the target (excluding class ability, dot as for example fire rune, rage, divine smite...) will increment by 2d12 necrotic
• all healing done to the target is doubled (includes spells, actions, potions, etc...)
• the target is under the effect of Enlarge spell
• all damage infilcted by Gurtogg Bloodboil to the target is doubled

Also Gurtogg Bloodboil gain the following buff from Fel Enrage for the duration of the Fel Rage:

• Gurtogg Bloodboil will focus only against the Fel Rage target, all his action wil have the Fel Rage target as main target
• Gurtogg Bloodboil gets resistance from all the type of source of damage
• Gurtogg Bloodboil heals himself for 32 (8d6+8) hit points
  

If the target dies (failing all death saving throw) or becomes invulnerable (under the effect of Invulnerability, teleportation to another Plane for more than two turns, Force Cage spell ...) the effects of Fel Rage ends immediately and the fight returns to the phase 1.
At the end of the Fel Rage, all bonuses to the target and to Gurtogg will be removed (for Fel Rage target health i.e. from above 70/180 --> 1/80).

Total 2 actions per turn.
