Use boon as a slightly formal noun for a welcome benefit. The adjective sense ('boon companion') is archaic and formulaic. Do not use boon as a verb.
Boon is a noun, not a verb — 'to boon' does not exist. In informal contexts, 'godsend' or 'blessing' are more natural. Do not confuse the noun and adjective senses, which have different etymologies.
Two distinct words share this spelling. The noun boon (benefit) comes from Old Norse bón ('prayer, petition, request'), related to Old English bēn ('entreaty'). The original sense was 'a favour asked for'; by the 16th century it had shifted to 'the favour or benefit granted', then to any timely blessing. The adjective boon (as in 'boon companion') comes from Old French bon ('good'), from Latin bonus.
What does boon mean?
As a noun, boon means a welcome benefit, blessing, or advantage — especially a timely or unexpected one: 'the new bus route was a boon for commuters'. As an archaic adjective, it means convivial or jolly, and survives mainly in the phrase 'boon companion'.
What is a 'boon companion'?

What is the opposite of boon?
The antonym of boon is bane — a cause of distress, harm, or misery. The pairing 'boon and bane' is a common literary device: something that is both a blessing and a curse.

No. Boon is only a noun or (archaically) an adjective. There is no verb 'to boon'. If you mean to give a benefit, say 'this change benefits...' or 'this is a boon to...'
