What is the highest damage multiplier you can get from type effectiveness?

If you didn’t get it, I mean the greatest amount of multipliers you can factor to base power, like STAB and super effectiveness. Like how Dry Skin Parasects are 5x weak to Fire types. You must include:

PS: Don’t include any boosts like bulk up, as these impact Atk/Sp.Atk stats, not base power.

Best I can come up with so far:

Victini in triple battle, inherits Pure Power from using Skill Swap, holding Metronome, after using Flame Charge 5 times, with one ally that has Flower Gift ability, both allies using Helping Hand on the same turn, during harsh sunlight, against Scizor with Dry Skin ability affected by Forest’s Curse.

Counting only things that are actually type multipliers, the best you can do in the current games isx16, achieved by using Forest’s Curse (Trevenant’s signature move) against a Pokemon like Scizor or Snom to give it a third type, Tar Shot (Coalossal’s signature move) to give it an additional Fire weakness separate from any type, then hit it with a fire move. The highest type multiplier that has ever been legally achievable in any game isx32, for which you have to play in an Inverse Battle (most easily done in gen 6), have Smeargle Skill Swap its own ability to Normalize (Delcatty’s signature ability), have the opponent send out an Aggron, then use Trick-or-Treat against the Aggron and finally hit it with Flying Press, which thus counts both Normal and Flying type matchups on the Inverse Battle type chart against Aggron’s Steel/Rock/Ghost typing. The programmers designed this field to hold values as large as x64, but there’s no way to reach that limit.

Other effects generally go into one of three places:move power multipliers,stat multipliers, anddamage multipliers.Move power multipliers include things like plates, other type-boost items, terrain boosts, Helping Hand, some ability boosts like Technician or Analytic, Dry Skin (against fire moves, it works as a move power multiplier on the opponent’s move), and Rollout’s escalating effect that can count up to x16 or even x32. Enumerating which of these multipliers can possibly coexist is complicated, variable depending on the game, and also not the point of the question.Stat multipliers include the basic stat stages; items such as Light Ball, Thick Club, and Eviolite; a different set of abilities like Overgrow or Solar Power; Thick Fat (when this ability applies, it’s actually implemented as a multiplier that reduces the opponent’s attacking stat), and Flower Gift in games where that ability is usable. A Marowak with +6 Attack, Thick Club, its ability swapped to Pure Power, and a Cherrim teammate for Flower Gift in sun will have an Attack stat multiplier of x24. If you’re playing gen 6 so that Triples exists, and give ittwoFlower Gift teammates at once, you can get to x36 that way.Damage multipliers include things at the end of the calculation after you’ve already combined the other numbers. This is where STAB and weather multipliers go, and they also include screens, Life Orb, yet another set of abilities like Sniper or Tinted Lens, and the opponent’s Solid Rock or Fluffy.

Forest’s Curseto the rescue!

A Scizor with Forest’s Curse taking a Flamethrower to tha face from Numel. (x6 Super Effective + STAB)

A Weavile with Forest’s Curse taking a Flying Press to tha face from Hawlucha. (x6 Super Effective + STAB)

A Malamar with Forest’s Curse taking a Bug Bite to tha face from Spewpa. (x6 Super Effective + STAB)

A Garchomp with Forest’s Curse taking an Ice Beam to tha face from Snorunt. (x6 Super Effective + STAB)

A Landorus with Forest’s Curse taking an Ice Beam to tha face from Snorunt. (x6 Super Effective + STAB)

An Altaria with Forest’s Curse taking an Ice Beam to tha face from Snorunt. (x6 Super Effective + STAB)

A Heracross with Forest’s Curse taking a Peck to tha face from Spearow. (x6 Super Effective + STAB)

If I think of anything else, I’ll edit it in

Counting hacks and such, this is the most boost you can have on a move
