arcane hot shot is slightly better than arcane acceleration but only with heat lizzie
archon vitality is comparable to a third strength mod on this setup but seems worse (keep in mind this is quadruple-dipping strength with roar, overdrive, and [Lizzie] herself; when combined with how many heat procs [Lizzie] does already, an extra heat proc per hit doesn't actually do all that much compared to 44% or 55% more str)

exilus is flexible ofc

replace [Augur Reach] with [Augur Secrets] for more str but less range

subsume was originally roar over pyrotechnics but that doesn't work (ripper's wail is counted as a damage buffing ability, and it's a major source of status dmg so subsuming over it isn't viable)
any cc, non-ehp survivability, grouping, or dmg amp (if not counted as "damage buffing") should be fine but i'm personally going with breach surge for more dmg bc i'm a gremlin
i don't think nourish is a good idea despite the increased raw dmg and viral procs; it fucks with the weighting, doesn't buff the actual damaging statuses, and lizzie can already prime viral herself with the aim cast

only needs 3 forma, move aura polarity instead of formaing over it
