Encounter-specific Details, Actions and Tactics
Lava surrounds the arena, dealing 12d6 fire damage if you enter it or end your turn in it. The squares adjacent to the lava are also intensely hot, dealing 2d6 fire damage when entering such a square or ending your turn in it.
Four vents of caustic smoke also dot the area. These are opaque enough to give creatures on opposite sides of the vent Concealment from each other. This Concealment can be used to Hide. Entering or ending your turn within a vent deals 2d6 acid damage.
In phase 1, Tekton begins his turns with Lacerate and Stomp on the same target, or Swipe on two different targets. His final action is often used to raise his shield. In niche cases, he may drop his shield to gain a free hand, to be used on Athletics manoeuvres (e.g. to Shove poorly positioned characters into the lava).
Once reduced to half health, he will move towards his anvil on his next turn, either using Trample and trying to damage as many players as possible, or simply Striding to it if he can reach it in one Stride, and begin using his phase 2 statblock.
In phase 2, he will always Sparkstorm on his turn if able. The remaining action will either be used to Stoke Flame (if the party is tightly grouped) or to Backhand + Improved Push (if there is a melee character who could be disrupted by this).
Room Description/Flavor Text
The first thing you notice about this room is the burning heat, as the green-ish grey cavern walls are lit by a moat of lava. Ruptures in the floor allow thick, caustic smoke to billow forth. And a massive being, wrought of flame and contorted into a massive suit of armor, stands at an anvil by the lava's edge. Hammering away at a massive longsword. It pauses for a moment, turning its head to you and discarding the hammer in favor of its sword.
