Lachlann Heavy Slam not well Telegraphed

You have established a gameplay language that unblockable attacks flash red with a good windup. This attack is a hard-hitting slam that cannot be blocked, yet it doesn't follow the rest of the game language for the player to read and respond to. Please give this move more telegraphing and the red flash that large, unblockable moves should have.

Loving the game difficulty, this is the only thing so far that has stood out as unfair. Please do not make the game easier, just fine tune what you have.

His double slam.
The audio cue (his words) are said after he starts the strongest attack. So the attack should either have a longer windup, or have the audio cue before. I'm in cruel now and it's one of the few attacks that is very hard to avoid.
