Portal source and chance
The item card says “Drops in Infinite mode: a 30% chance every 10 waves.” A chance is not a guaranteed Portal every ten waves and does not tell you how many attempts your account will need. The related Infinite milestones also include wave 25 and wave 40 titles.

Open it in the Tree Fort
The use instruction says a route into the Lich’s Lair opens where you stand in the Tree Fort. Check your Portal inventory, go to the Tree Fort and use OPEN PORTAL when available. In the captured state the inventory is zero and the button is grey; that is not evidence of an opened Portal or a completed Lair run.
The Lair reward text lists one Lich Ooze per win and a 5% chance to get the Secret Lich. The 30% Portal chance and 5% hero chance belong to different events and must not be treated as the same roll.
What Lich Ooze is for
Lich Ooze’s description identifies it as The Lich’s evolution item and names Jake the Lich as the target. It points back to winning in the Lich’s Lair through a Portal, one per win. A full evolution quantity, Gem fee and completed evolution are not shown. Consult the item and evolution reference before collecting unrelated hero materials.

Read a joined Lich Portal party
The new screenshot shows an already joined Tree Fort portal party: THE DEAD WASTELAND, 3/4 players, an owner crown, “Waiting for Elysia to enter” and a LEAVE button. Wait for the owner rather than treating this state as a started match. This documents the room state, not the use of the current player’s own Portal item.
The room states “Win: 5% chance of the SECRET Lich!” This chance is conditional on winning; joining alone does not grant the hero. The earlier item description calls the destination the Lich’s Lair, while this actual room is titled The Dead Wasteland. Keep these two visible names with their respective contexts rather than inventing another map relationship. No clear or Secret Lich drop is shown.
