Evomon: A Song of Ice and Fire Quest Walkthrough (V1.2.5)

Evomon’s V1.2.5 patch adds a mid-season story quest called A Song of Ice and Fire, and it runs almost entirely inside the Polar Rift. It mixes three clue pickups, an elemental portal puzzle, two forced battles, and a short raid-style fight where the wrong attack type does nothing at all. The last part is where most players stall, because the game expects you to read a color and respond with its opposite.

Quick answer: Teleport to Polar Rift in the Seasonal Isles, talk to Mentor Ben, collect the diagram, map, and Lilian’s notebook, solve the portal puzzle with the elemental cycle, clear the Frostins, then stabilize the engine using Fire-type attacks while it glows blue and Ice-type attacks while it glows red.

What you need before starting A Song of Ice and Fire

The quest lives in Polar Rift, part of the Seasonal Isles, and you reach it through the teleport menu rather than by walking. Bring a team that covers both Fire and Ice damage. That is not a suggestion for efficiency, it is a hard requirement for the final encounter, since the engine only responds to the element opposite to its current state.

The enemy levels give you a sense of the gear check involved. The Secret Zone opens with four level 180 Frostins, and a second fight later drops to level 120 enemies. Fire-type attackers such as Magmaxor and Ignibud carry most of the work against the ice-themed lineup.

Polar Rift clue locations and quest steps

Teleport to Polar Rift and speak to Mentor Ben to open the quest. He points you toward the characters who hold the first pieces of information, so there is no need to explore the map blindly at this point.

Find Icelet and Sparky in the same area and talk to both. Their dialogue hands over the diagram and the map clue, which are the first two of the three items the objective tracker asks for.

Track down Lilian’s notebook, the third clue scattered around Polar Rift. The objective panel counts your progress as you interact with each one, so use it to confirm you have not missed a pickup before moving on.

Head to the portal in the Secret Zone with all three clues in hand. The gate stays locked until the puzzle is solved, and the clues are what tell you which elemental combinations the gate accepts.

How the portal puzzle works

The gate runs on an elemental cycle rather than a code you can brute force. Each clue describes how two elements combine into a third, and you input those pairings on the portal gate. Combining Wind and Ice to produce water is the example the puzzle teaches you with, and the rest of the inputs follow the same logic.

Before the gate opens, a fight breaks out against four Frostins at level 180. Fire coverage clears it quickly. Once the portal unlocks, a second battle waits inside the Secret Zone against level 120 enemies, which is a noticeably easier check.

After the Secret Zone fight, a cutscene plays in which a jester-like thief takes the Equilibrium Core and escapes. Lilian then explains that the thief made off with both the original Core and its replacement, which is the reason the region’s climate has gone unstable.

Engine stabilization raid: match the opposite element

The finale is a raid-style encounter against a machine that shifts between two states. The rule never changes, and reading the color correctly is the entire fight.

Engine color	Engine state	Attack type to use
Blue	Ice	Fire-type moves
Red	Fire	Ice-type moves

Note: the banner above the engine tells you which element it wants at that moment, so you do not have to guess from the color alone. Swapping to the correct attacker as soon as the state flips is what keeps progress moving.

Quest completion check and rewards

Once the engine is stable, return to Lilian for the closing dialogue. A “Quest Complete!” banner appears on screen followed by the reward summary, which is the confirmation that the quest has actually registered rather than leaving an objective open.

EXP	550

Common reasons the quest does not progress

Not all three clues collected. The diagram, the map, and Lilian’s notebook are separate pickups, and the portal stays shut until the counter is full.
Entering the engine fight without both Fire and Ice attackers, which leaves you unable to answer one of the two states.
Attacking with the same element the engine is displaying instead of its opposite.
Skipping the final conversation with Lilian, since the rewards only pay out after that dialogue closes.

V1.2.5 ships more than the story beat. The patch also refreshes raid enemy lineups, adds new EX trials, and includes quality-of-life changes to auto-hunt. The story quest is the shortest piece of that package, but the engine mechanic it introduces is the part worth learning, because it is the same read-and-respond pattern the updated raid content leans on.
