What went wrong?

For example, opening from RuneLite will not allow us to know what darts the player is using (there is no client-side varb or varp for this, afaik), so it will open the calculator with a blowpipe equipped but no darts (runelite/runelite#17688).

What did you expect to happen?

We should essentially no-op when someone chooses the normal blowpipe with no specific ammo type, and show no DPS. We should also show a warning (probably by adding a UserIssueType) to inform the user.

What browsers are you seeing the problem on?

Firefox

What device(s) are you seeing the problem on?

Windows
