Heavy Blade Opportunity & Twin Strike

[Prestidigitalis]

Sadly (or is it fortunately?), the HBO feat says:

When you make an opportunity attack with a heavy blade, you can use an at-will attack that has the weapon keyword instead of a basic attack.
​

Sword Burst has the Implement keyword, not the weapon keyword.

Otherwise, it would just be grotesque.

HBO also rocks with swordmage powers.

Booming Blade on an OA is basically extra free damage.

Actually no, Booming Blade (and Frigid Blade) don't work fully with HBO. You can attack with Booming Blade (or Frigid Blade) during an AO if you have the HBO feat, however the secondary damage (or the movement reducing effect) does not apply on such uses of the power.

Because they apply only if the enemystarted it's turn adjacent to the swordmage while under the effect of the power. However to provoke an OA the start of the enemy's current turn is already over, thus he can't start a turn adjacent to the swordmage until his next turn.

DOH!

Good catch!
