Ice and Fire: DragonsFire / ice / lightning dragons, plus a bestiary of mythical creatures

Mod version: 2.1.12 + patch-1 · MC 1.16.5 · Forge 36.2.34 · Java 8 · 1.16.5 = the 2.1.x branch — newer 1.20.x versions added creatures we don't have.

About

Ice and Fire adds three full dragon species — Fire (deserts / badlands), Ice (frozen biomes), Lightning (savannas) — each with 5 growth stages and roosts/caves to defend. Stage 1-3 dragons patrol the surface, stage 4-5 wait in underground caves with massive treasure hoards. Drops include Dragon Bones, Dragon Skull (giant decorative), Dragon Blood (potion-tier ingredient), and Dragon Scales (best armor in the mod).

Beyond dragons: Sirens (lure swimmers off cliffs), Cyclopes (giant sheep-herders in their cave), Gorgons (turn-to-stone gaze), Hippogryphs (rideable), Hydras, Stymphalian Birds, Pixies, a Cockatrice. Each has its own loot table and combat puzzle.

Things to do

Craft a Bestiary: 3 Manuscripts (loot from Dragon Roost chests) → bound in a book. Permanent guide that fills in as you encounter creatures.
Hunt a Stage 1-3 dragon for Dragon Bone (sword, bow), Scales (armor tier above diamond), and Skull (decor)
Tame a Hippogryph for a flying mount
Raid Dragon Caves for Stage 4-5 dragons — they sit on millions of gold & gem piles
Collect a Dragon Egg (only from female Stage 4-5), hatch via the matching element: fire egg in lava, ice egg in water, lightning egg in rain
Craft elemental swords: Fire Sword (Dragon Blood + Blaze Powder), Ice Sword, Lightning Sword

Getting started

From OneBlock you'll need to portal to a real dimension (Twilight Forest, or a Mining Dimension) to find dragons — the OneBlock terrain itself won't spawn them. Bring iron-tier gear minimum. Fire Dragons are easiest first: Fire Resistance potions fully neutralize their breath attack. Get the Dragon Seeker compass-like item if you can't find one. Always sleep within range of a respawn anchor before going in; Stage 4-5 dragons one-shot unprepared players.

Videos

Most YouTube guides for this mod were recorded on 1.12.2 (the original release) or 1.20.1 (the modern port). Both eras differ in small details (loot tables, taming mechanics) from our 2.1.12. Trust the in-game Bestiary over outdated videos when in doubt.
