The 5 rooms of Royal Mastogob's Greenhouse
Five Mastogob rooms. The last two are the most crowded, with 60 and 30 obstacles: positioning counts double there. For each room: the scenery, then the tactical view with the starting cells (blue: you, red: the monsters). Tap an image to enlarge it.

Room 5 — the Royal Mastogob
The Royal Mastogob, invulnerable from the start of the fight. Push it to make it vulnerable, without ever slamming it into an obstacle or an ally: the strategy is detailed just below.
Defeat the Royal Mastogob
The push damage that kills
If the Royal Mastogob takes push damage, the characters lined up with it die, and Berserkgob deals 100 damage to its allies for one turn. Always push it into the void, and never push a character against it: the effect is the same.

It is invulnerable for the whole fight, except for one turn after each push, and then gains 4 MP. Regrougob pulls characters around it, Lichegob steals life on contact, and Randon summons a Mastogob that strengthens it. Weak point: Water (-11%); it resists Air by 48%.
Regrougob5 AP · on self · Pulls 3 cells ·-1 MP · 57 to 67 Water damage
Pulls all characters in a cross up to 3 cells around the Royal Mastogob, removes 1 MP, and hits. Cooldown: 3 turns: spread out.
Lichegob5 AP · on self ·66 to 75 Fire steal
Life steal in a cross on contact, once per turn. Don't end your turn next to it, especially after a push that gives it MP.
RandonSummons a random Mastogob up to 3 range, cooldown 3 turns. The summon boosts it; once killed, it leaves it with a permanent penalty.
The four-step strategy against the Royal Mastogob
Positioning. Regrougob pulls characters in a cross up to 3 cells around it and Lichegob hits on contact: never group up near the Royal Mastogob. Each of you should keep an escape cell.
Kill its summons. From turn 1, then every 3 turns, it summons a Mastogob that gives it a bonus. Killing the summon removes that bonus and gives it a penalty until the end of the fight: MP, power, critical, or damage taken.
Open the window. Push it: it is vulnerable from the start of the pusher's turn until that same character's next turn. A pusher who plays early in the initiative lets the whole team hit afterward. Each push also gives it 4 MP, stacking.
Hit with Water. During the window, concentrate your damage, preferably Water, its only weakness. Then move away: with its extra MP, it can reach you before becoming invulnerable again.
Randon: buffs and debuffs
The Royal Mastogob summons one of the dungeon's monsters at random. As long as the summon is alive, it gains a bonus: 1 MP for a Mastogobbly, 5% less damage for a Mastogob Warrior, 20% critical and 30 critical damage for a Venerable Mastogob, 200 power for a Mastogob.
When the summon dies, the bonus disappears and the opposite penalty applies until the end of the fight: -1 MP, 5% more damage taken, -20% critical and -30 critical damage, or -200 power. Each summon killed weakens it permanently.

Special: Royal Parsimony
An ally who moves an enemy during their turn must no longer deal damage to it until the end of that turn. One character pushes the Royal Mastogob, the others hit it without moving it. Do not move the other enemies unless it is an emergency; in that case, do not hit the moved enemy anymore for the rest of your turn.
First
The Royal Mastogob must be finished off first. No monster or summon may die before it. Hit the Royal Mastogob during every vulnerability window, and control Mastickle's heals without finishing off the other targets.
Clean Hands
Enemies must be finished off without direct damage: traps, glyphs, poisons, push damage, reflected damage, and summons are allowed. Weaken the enemies normally, then finish them with a poison, a trap, a glyph, or a summon. On the Royal Mastogob, forget push damage: it kills the characters lined up with it.
Duo
Two characters maximum, fewer than 20 turns. With two characters, control the summons and take advantage of every vulnerability window to hit fast. Everything must be finished by the end of turn 19.
