Dose of Dawnglow — ruling 1

The creature you choose to put -1/-1 counters on doesn't have to have enough toughness to survive the process. For example, if you blight 2, you can choose to put the counters on a 1/1 creature you control.

Dose of Dawnglow — ruling 2

If you can't place -1/-1 counters on any creatures you control (probably because you control no creatures), you can't choose to blight.

Dose of Dawnglow — ruling 3

If a creature that has +1/+1 counters on it receives enough -1/-1 counters to cause it to be destroyed by lethal damage or put into its owner's graveyard for having 0 or less toughness, effects that refer to the counters on that creature when it died will see all of those +1/+1 and -1/-1 counters.

Dose of Dawnglow — ruling 4

Once you've announced that you're casting a spell or activating an ability, players can't take actions until you've finished doing so. Notably, opponents can't try to destroy or otherwise remove your creatures to stop you from blighting as part of paying the cost of that spell or ability.

Dose of Dawnglow — ruling 5

All of the -1/-1 counters must be put on a single creature. You can't choose to split them up between multiple creatures.

Dose of Dawnglow — ruling 6

If a creature has +1/+1 counters and -1/-1 counters on it, state-based actions remove the same number of each so that it has only one kind of those counters on it. For example, if a creature has three +1/+1 counters on it and two -1/-1 counters are put on it, state-based actions will remove two of each of those kinds of counters, leaving the creature with just one +1/+1 counter.
