Breach the Bastion Spire Deck Builder Pre-Run Checklist

Wipe less by deciding the boring stuff before Breach the Bastion generates your map. This checklist is built for solo practice and for four-player lobbies alike. Copy it into Discord, mark each box, then path with intent.

1) Account & codes

• Correct Roblox account selected (especially if you keep an alt for scripts).
• Game updated / rejoined fresh server.
• Active codes redeemed via Menu �?Codes �?currently 1KCCU for Random Map Ink; skip expired 500CCU (Codes Hub, How to Redeem, Map Ink Guide).
• Map Ink presence confirmed so you are not redeeming mid-act.

2) Class pick

• Class chosen for tonight’s goal (learning Brewer vs comfort kit).
• If Brewer, skim Brewer Class Guide for Spores / Stand Guard / burst timing.
• Compared options on Classes Tier List without slavishly forcing an S-tier you dislike.
• Cosmetic / loadout distractions closed—HUD clear.

3) Deck plan (one sentence)

Write a single plan such as:

• “Thin starter strikes, take two defense, one finisher by Act II.”
• “Brewer: Spores package into Spore Burst; skip pure greed rares.”
• “Elites for relic; merchant remove before boss.”

Rules:

• Plan written in party chat or sticky note.
• Know your must-take card types and auto-skip types.
• Agree when to break the plan (e.g., free Happy Flower-style relic).

4) Path risk mode

Pick one primary bias:

Mode	Take when	Avoid when
Safe	Learning a class, low potion count	You desperately need relics
Elites	Deck already stable, hunting relics	HP already red after hallway
Rush	Testing burst windows quickly	Co-op teammates need rests

• Mode announced.
• Rest policy set (“rest under 50%�?or “rest only before boss�?.
• Elite cap set (“max one elite before first merchant�?.

5) Potion policy

• Who carries which potion in co-op (no four strength pots, zero blocks).
• Panic threshold defined (“potion under 30% HP�?.
• Boss potion reserved—do not burn it on a hallway because auto-habit says so.
• If using any automation, disable auto potions until you trust the threshold (Scripts Hub).

6) Co-op callouts (skip if solo)

Breach the Bastion allows up to three friends (four players total). Before ready-up:

• Path lead named.
• Burst / guard / economy roles lightly assigned (Tools Hub role sheet).
• Ping vocabulary agreed: “elite�? “rest�? “merchant�? “event�? “skip card�?
• Rule for contested rewards: path lead breaks ties unless someone needs a class piece.
• Read Co-op Guide once per major patch.

7) Mid-run gates

At each rest or merchant, re-check:

• Still on the announced path mode?
• Deck still matches the one-sentence plan?
• Potion slots still correct for the next elite/boss?
• Anyone need a bio break before a boss node?

If two gates fail, downgrade to safer nodes instead of ego-pathing.

8) Post-run note (2 minutes)

• Cause of death / victory margin written (“no block vs elite�? “greed skipped remove�?.
• One card you should have skipped.
• One path decision you should repeat.
• Codes / checklist tweaks for tomorrow.

Quick solo version

Pressed for time? Minimum viable checklist:

1. Redeem 1KCCU if not done.
2. One-sentence deck plan.
3. Pick safe / elites / rush.
4. Potion panic threshold.
5. Rest under 50% until Act II.
