User blog comment:Sidamhcuot/SP build for the sphere originators/@comment-35295780-20180527205452

Hello there. Here is my opinion:

Amadream: Take the 80% boost to all parameters, probable resistance against 1 KO attack and powerful additional attack (DoT) at turn's end effect for 3 turns to BB/SBB (100 sp). You won't really use her outside arena/colosseum so this would be the best bild for her. IF you have Behemoth (with DoT sphere) in arena/colosseum then you can take the adds probable random status ailment infliction effect to SBB instead of the DoT (115 sp).

Daltisk: Take the 60% boost to all parameters, huge Def boost relative to Atk for 3 turns effect to BB/SBB and huge Atk boost relative to Def for 3 turns effect to BB/SBB (80 sp so far). You can take either the huge BB Atk boost for 3 turns effect to BB/SBB or the huge all elemental damage (EWD) boost for 3 turns effect to BB/SBB (115 sp). If you don't need the BB atk boost and the EWD boost than you can take the boosts Atk, Def relative to remaining HP and activates at turn's end effects during turn's start instead (100 sp)

Zegstia: Take the 80% boost to Atk, max HP, 170% boost to Spark damage, raises Atk parameter limits to 180000,   huge all elemental damage boost for 3 turns effect to SBB and raises normal hit amount(90 sp). This bild is good for both Sbb and normal atk nuking. For the rest you can decide what to take.

Wintia: Take the 80% boost to Def, max HP, probable resistance against 1 KO attack, enhances BB/SBB's slight all elemental damage reduction and enhances SBB's Spark and additional damage reduction effect (110 sp). This bild is good for both arena/colosseum and for hard contents. For a pure arena bild, take the 80% boost to Def, max HP, Probable resistance against 1 KO attack, 50% Spark damage reduction, Adds damage reduction and Negates Def ignoring damage/Negates critical and elemental damage (110 sp).

Limilnate: Take the 80% boost to Def, Rec, max HP, damage taken boosts BB gauge, adds fills own BB gauge to max effect to BB/SBB so that he can refill his bb/sbb easier. Take the adds high probability of resistance against 1 KO attack effect to UBB because this is really usefull in some difficult dungeon. If you have this skill covered by another unit than you can take either the adds huge boost to Rec for 3 turns effect to BB/SBB or the adds huge Atk boost relative to Rec for 3 turns effect to BB/SBB and the adds Earth barrier effect to BB​​​​​​​.

Roglizer: Take the 100% boost to all parameters, 150% boost to Spark damage, adds Spark damage boosts BB gauge for 3 turns effect to BB/SBB and '''raises Atk parameter limits to 180000. If you didn't reach level 999 yet and if you are planning to reach it the take the enhances LS's huge EXP boost effect (otherwise don't). '''For the rest it's up to you.

I hope it helps.
