How to Get Eternity T4 Weapons in MapleStory : Idle RPG

To get an Eternity T4 weapon in MapleStory : Idle RPG, you must level up your weapon summon pool until Eternity items appear in the drop table, then merge duplicate lower-tier Eternity drops through equipment synthesis. Raw drops for top-tier weapons have exceptionally low probabilities, making synthesis your most reliable path to obtaining T4 gear.

Leveling the Weapon Summon Pool

The weapon gacha operates on a progression track where every summon ticket or red diamond spent awards experience toward your summon level. High-tier items do not drop at early summon levels.

Before spending red diamonds on mass summons:

• Open the weapon summon interface and inspect the drop rate table.
• Confirm that Eternity weapons are listed among the obtainable outcomes for your current summon rank.
• If Eternity gear is not yet in the pool, treat your pulls strictly as investments to earn summon experience rather than hunting for a direct drop.
• Spend weapon summon tickets immediately as you acquire them to advance your pool level without draining diamonds.

Merging Weapons Through Equipment Synthesis

Because pulling an Eternity T4 weapon directly is rare, progressive synthesis serves as the primary acquisition method. You can merge identical lower-tier weapons into the next numerical tier, turning duplicate Eternity T1, T2, and T3 drops into your target weapon.

To combine weapons safely:

1. Lock your currently equipped weapon in your inventory so it cannot be consumed as synthesis material.
2. Accumulate duplicate Eternity T1, T2, and T3 weapons from gacha pulls and summon milestones.
3. Keep all Eternity-grade drops; do not salvage or dismantle any item in the Eternity bracket.
4. Use the auto-combine function to merge lower tiers upward until you create an Eternity T4 weapon.

When to Invest Resources in Eternity Pulls

Chasing Eternity T4 gear requires a massive volume of pulls. Shifting all your red diamonds into weapon summons too early can stall your overall account progression.

Hold off on heavy diamond spending until your basic setup is functional:

• Stabilize your core damage skills with adequate skill levels.
• Unlock necessary companion presets for both general stage farming and boss fights.
• Establish basic artifact sets to ensure consistent baseline stats.
• Reserve diamonds for daily essentials, such as dungeon resets, stamina refills, and shop priorities.

Once those foundational systems are in place, direct your surplus red diamonds into weapon summons—ideally during summon rebate events or rate-up updates—to push through the remaining pool levels and gather the Eternity duplicates needed for synthesis.
