NPC clusterMedjed + Calypso + Captain Trotter + Tutorial Terry + Jerry mark the chapter mid-point
The temple entrance is the Chapter 4 mid-cutscene zone. Per Miraheze's Notable Characters field, the four NPCs that appear in the temple are Medjed (the Egyptian-themed vendor who sells cards and items, sitting near the entrance), Calypso (the locked party member for the Temple Guardian fight, who joins here and stays through The Ancients), Captain Trotter (post-lava, available as an NPC for the Firebrand follow-up dialogue), Tutorial Terry (returning chapter 4 tutorial trigger), and Jerry (the recurring Block Tales protagonist for the chapter progression dialogue). The Calypso dialogue here is what triggers the Temple Guardian locked-party mechanic - the encounter is hard-coded to lock Calypso into the player party for the duration of the fight, and you cannot swap her out or call a different summon during the Guardian's split phase. Plan the build around Calypso's survival, not the player's damage output, because the encounter's win condition is the Calypso-stays-alive check rather than a pure HP race.
Boss encounterTemple Guardian + Left Hand + Right Hand three-body split with Calypso locked party
The Temple Guardian fight is the chapter's only three-body boss and the only Chapter 4 encounter where the player is locked into a specific ally. Per Miraheze, the encounter is Temple Guardian (the main body with the orange-mouth laser tell that opens every cycle) + Left Hand (the left sub-body that applies DEF Down to adjacent targets) + Right Hand (the right sub-body that applies the multi-hit Smash follow-up). The reliable counter pattern is: (1) bring cards that work in all three body phases, not just the Guardian, because the Left Hand and Right Hand each have at least one turn that punishes under-equipped parties, (2) treat Calypso's survival as the win condition rather than the boss HP race - she goes down hard in the second wind if you do not peel for her through the orange-mouth laser phase, (3) plan two self-heal cards and one shield card stacked for the second wind, and (4) the Ancient Key drops on encounter clear, not on encounter start, so the badge run cannot progress to The Ancients without surviving the full Temple Guardian cycle. The fight's split-phase pattern is what the Calypso-Death Check on the Chapter 4 Nirvana badge route references - the badge requires both Calypso survival AND the encounter clear, in that order.
Boss sequenceTemple Guardian three-body -> The Ancients lower-tomb chapter final boss
The canonical Chapter 4 boss sequence in this region is Temple Guardian (the three-body split fight at the temple arena) followed by The Ancients (the lower-tomb chapter final boss, gated behind the Ancient Key that drops from the Shovel Area puzzle). Per Miraheze's Bosses index, The Ancients is the Chapter 4 Final Boss and lives in the lower excavation layer that the Ancient Key unlocks - the encounter sits immediately after the Temple Guardian cycle resolves. The Ancients is the chapter's main story boss, and the Temple Guardian + The Ancients pair is what pulls the steady 'temple of the red sun block tales' / 'temple guardian block tales' / 'the ancients block tales' search traffic during the Chapter 4 badge runs. Plan the build to cover the three-body Temple Guardian + The Ancients final boss in one rotation - the chapter does not let you respec between the temple arena and the lower-tomb layer.
EnemiesAnubis, Scarab, Camel?, Ramblin' Pot - Egyptian-themed trash that punishes under-healed parties
The Temple of the Red Sun's trash mobs are Egyptian-themed and harder than the Ch4 preceding zones. Per Miraheze's Enemies field, the four enemy types in the temple are Anubis (the ranged caster that applies Sand status on multi-hit), Scarab (the fast swarmer that spawns in packs of 3-4), Camel? (the joke-name mini-boss spawn, mid-HP with a charge stomp), and Ramblin' Pot (the throwable object that bounces off walls and applies DEF Down for 2 turns). The reliable counter pattern is one multi-target burst card (to clear the Scarab swarms before they chain), one dispel or shield card (to drop the Sand status from Anubis and to absorb the Camel? charge stomp), and one ranged poke or item-damage card (Bombs deal 3 damage to the Scarab swarms without triggering the Ramblin' Pot bounce counter-attack). Solo players should swap one heal for a self-revive - the Anubis Sand status stacks for 3 turns if not dispelled, which is what most 'temple of the red sun block tales' Reddit threads cite as the chapter's mid-difficulty wall.
Build shellOne deck that survives Temple Guardian three-body + The Ancients final boss without re-speccing
The reliable Temple of the Red Sun shell is one multi-target burst card (to clear the Scarab swarms and to chip the Temple Guardian Left Hand + Right Hand in the same turn), two healing cards (Temple Guardian's orange-mouth laser, The Ancients' lower-tomb phase, and the Anubis Sand stacks each have at least one phase that punishes under-healed parties), one dispel or shield card (to drop Sand status from Anubis and to clear the DEF Down stacks from Ramblin' Pot), one ranged poke or item-damage card (Bombs deal 3 damage without triggering the Camel? charge counter, and Firebrand - if Captain Trotter is already cleared - is the recommended pairing for the Temple Guardian orange-mouth phase), and one self-revive or shield-break card (the Calypso-Death Check on the Temple Guardian second wind is the canonical Chapter 4 mid-boss wall, and a single self-revive on the laser cast animation is the difference between a clean Temple of the Red Sun clear and a re-run). Use the build maker to confirm BP, SP, heal, dispel, and Firebrand coverage before crossing the Red Sun Bridge or attempting the Shovel Area puzzle.
