Insulatle is a recurring spell in the Dragon Quest series. It decreases the damage dealt by breath attacks by a substantial amount in all appearances, with the exact percentage varying between titles. Contrary to what the name implies, Insulatle reduces the damage of all breath attacks and not just fire and ice.


Dragon Quest III[edit]

Insulatle is learned by Priests and Sages at level 32, and costs 6 mp to cast. In the original version the spell will reduce damage by 33%, overriding any additional reductions provided by armour. This bug is fixed in all subsequent versions, and the spell will last 6~9 turns in all versions.

Dragon Quest IV[edit]

Insulatle is learned by Meena at level 29, costs 6 of her magic points to cast, and lasts for 6~9 turns. It reduces damage by 50%, setting the precedent for nearly all future appearances.

Dragon Quest V[edit]

Insulatle costs 3 MP, decreases breath damage by a massive 70% in the original Super Famicom release before being nerfed to 50% in all subsequent versions. This is likely the reason why armour resistances are weaker than usual in V.

Dragon Quest VI[edit]

This spell is obtained by advancing to Rank 2 of the Sage vocation, and once more costs 3 MP to cast. In addition to breath attacks, the spell also cuts Tidal Wave and Big Banga in half.

Dragon Quest VII[edit]

Insulatle features the same traits as in the previous game but now lasts 6~9 turns. It is once again learned by reaching rank 2 of the sage, but in the 3DS remake it can also be attained by reaching rank 3 of the Armamentalist, rank 3 of the Monster Masher, rank 1 of the Druid, rank 1 of the Hero, rank 4 of the Vigilantern, and rank 5 of the Gripevine vocations.

Dragon Quest VIII[edit]

Insulatle is learned by Jessica at level 25 and costs 3 MP. It lasts 6~9 turns, and can be replicated by Munchie's Chunky cheese.

Dragon Quest IX[edit]

Insulatle is learned by rangers at level 26 and priests at level 43. It reduces breath damage by 25%, capping at 50% when cast twice, and costs 8 mp to cast. The effects of the spell will last for 6~9 turns.

Dragon Quest X[edit]

Dragon Quest XI[edit]

Rab learns Insulatle at level 40 and cuts breath damage by 25% once more, but now costs 12 MP to cast.

Dragon Quest Monsters[edit]

Insulatle (then know as Barrier) is learned by monsters beginning at level 18 if the monster has at least 76 MP and 70 Intelligence. It is learned naturally by AmberWeed, KingSlime, MistyWing, WeedBug, and WindMerge. [1]

Dragon Quest Monsters 2[edit]

Barrier now requires 126 intelligence to learn. It is naturally learned by the Aquarella. It is no longer naturally learned by the Genosidoh, KingSlime or WindMerge.
