History of Bonus Action

Bonus Action is a triumph for completing and acquiring all Seasonal bonuses.

How to complete

The exact list of "Seasonal bonuses" was not found in the sources opened. Related Portal objectives are the Bonus Focus triumphs (Bonus Focus I, Bonus Focus: Solo Ops, Bonus Focus: Fireteam Ops, Bonus Focus: Crucible) and Bonus Drops III; these are plausibly the bonuses it tracks but that link is unconfirmed.

Notes

Seal/category and reward are unconfirmed. See the Portal and Seasonal Hub for how bonus rewards work: bonus rewards show on Portal activities before you start them, and performance grade affects whether you receive them.
