Since monsters went multitarget, concepts of Epic Boss and Epic World have changed somewhat.

Epic Boss is still relevant monster type in that summoning is done using summon orb gained through quest. Just as well, Epic World is relevant as summoning is done either using items gained as gifts, as loot from somewhere, or by expending energy.

But Epic Boss of multitarget type (eg. Fenix) doesn't use monster pool of 1 but rather mpool=101, which is the same as any multitarget type Epic World monster (eg. Abomination).

This means that it's possbile to summon three Epic Boss monsters at the same time: Alpha Mephistopheles (mpool=3, most likely a typo by devs that was never fixed), any other Epic Boss before Fenix (mpool=1), and any other Epic Boss from Fenix on (mpool=101).
