Tenebrous form vs Second Tradition

A lasombra is bleeding, then a prince burns 1 blood and untaps and attempts to block with second tradition: domain.

The lasombra then plays tenebrous form.

Is the filthy camarilla prince obliged to burn the blood due to second tradition, that say's he "attempts to block"? Or he can back out and give up the block attempt?

thanks!

Name: Tenebrous Form
Cardtype: Action Modifier
Cost: 1 blood
Discipline: Obtenebration
[obt] +1 stealth.
[OBT] As above, and minions without Obtenebration [obt] must burn 1 blood to attempt to block (allies cannot burn blood).


Name: Second Tradition: Domain
Cardtype: Reaction
Requires a prince or justicar.
+2 intercept. Also usable by a locked prince or justicar, even if intercept is not yet needed, to burn 1 blood to unlock and attempt to block with +2 intercept.

Controller of the Prince can choose to burn the blood and continue attempting to block or decline to block and not paying for the blood required by tenebrous form

This ruling seems wrong to me, as far as I’m aware an attempt to block cannot just simply be aborted …once started it either succeeds or fails

Furthermore the attempt to block has already been started in the given scenario which makes no sense that it has to be paid for retroactively… if I’m not wrong one doesn’t need to “continuously” attempt to block once the attempt has been announced…would be illogical as it is a impulse resetting effect and would mean the attempting to block minion cannot do anything but announce an attempt to block every time they get the impulse.

“Attempt to block” as a reaction effect is not the same as “attempting to block” as an ongoing state… but I could be wrong

Well the Second Tradition forces the vampire to attempt to block once you play the card, so if Tenebrous form was played before than the locked prince needs to burn 2 bloods (one for second tradition and on for tenebrous form) but if Second tradition is played before Tenebrous form the card only force you to attempt to block at the moment you play it, after that you continue blocking if you fulfil all the conditions (like having enough intercept) but if the conditions changes, and with the must burn blood clause of Tenebrous form they changed, the controller decides as the force of the second tradition has already been dealt with

It's strange because the wording on the card does not say you have the option to back out. Only say that you MUST TO.

But attempts to block are optional, but you usually can't back out of a second tradition domain attempt to block. So why can you now back out?
