The haste spell states:
Choose a willing creature [...] it gains an additional action on each of its turns. That action can be used only to take the Attack (one weapon attack only) [...] action.
Stalker's Flurry states (emphasis mine):
[...] Once on each of your turns when you miss with a weapon attack, you can make another weapon attack as part of the same action.
If you take the Attack action with haste, and miss with the attack, can you then use Stalker's Flurry or does the "one weapon attack only" clause of haste overrule using the feature?
