Last Bible II fusion

Fusion in Megami Tensei Gaiden Last Bible II turns two monsters in the party into one. 101Leafy researched the game and tried fusions out in play. The Game Boy and Game Boy Color versions fuse the same way. The calculator takes the levels the two monsters have now; picking a monster fills in the level it joins at.

For monster fusion you have to use Saphia's spell Combine or ask a monster fuser. What sets it apart is that the stats of the new monster change with the phase of the moon at the time of fusion.

Fuse two monsters

Ways to make a monster

Rules

  1. Fuse through the fusion NPC, the spell Combine (5 MP), or a Mute Seed. The Mute Seed only works in two places in the game. Mark two monsters in the party.
  2. Every monster belongs to a race. Races 1 to 7 hold 20 monsters each and the elementals are the eighth. The chart gives the race of the result. Humans, the oni from Jaki to Ra-Ou, bosses, eggs, and the monsters that join through events or eggs can't be fused.
  3. The mutation race, Lich to Zenon, only fuses within itself.
  4. Two monsters of the same race make an elemental. An elemental and a monster of races 1 to 7 make a monster of that race. Two elementals make race 7.
  5. Normal fusion: the two levels the monsters have now are added, halved, rounded down, and 2 is added. The result is the first monster on the result race's list at that level or higher. If none is that high, it is the last one on the list.
  6. Elemental fusion: levels don't count. The result is the monster one step up or down from the partner on its race's list. Erthys, Aquans, Ukobach, and Jinn step down for races 3, 6, and 7 and up for the rest. Aeros, Flaemis, Golem, and Ifrit step down for races 1, 2, 4, and 5 and up for the rest. At the end of the list there is no step, so the result is the partner itself and the fusion fails.
  7. The leader's level plus 7 must reach the result's level.
  8. A monster that is already in the party can't be made. That includes the two being fused, so a pair whose result is one of them fails.
  9. Mutation: the fusion NPC never mutates. Combine has a 10% chance where the chart has a *. A Mute Seed always mutates. The result is then the first monster of the mutation race at or above the normal result's level, as long as that one is not already in the party.
  10. After a story event, the special fusions come first. They skip the chart and the leader check.
  11. Both monsters leave the party. The new one joins at its starting level with its starting stats, plus the moon bonus below, up to 49 in each stat. Depending on the gear the two had, it can also get a few points of Endur or Stren.

Race chart

Find one monster's race in the rows and the other's in the columns; the order does not matter. Each cell is the race of the result. * marks a 10% chance of a mutation with Combine.

Race lists

The monsters of each race in list order, with the level fusion compares against.

A mutation turns the result into the first monster of this list at or above the normal result's level. These monsters also fuse with each other by the normal rule.

Special fusions

Once a story event opens them, these pairs give a fixed result in either order. Which event that is has not been worked out yet.

Moon bonus

The moon phase when the new monster joins adds to or takes from four stats. The full moon makes strong monsters and the new moon smart ones. The Full Moon item sets the full moon.

Eggs

An Egg in the party can't die: damage to it stops at 1 HP. Each time another party member takes damage, the Egg gains twice that much HP. When it reaches its max HP, 95 to 108, it hatches.
