Okay so firstly to clarify for Thorgrim's AP, the 510 gigaton feat comes from an ultra casual feat as it's literally just a by-product of a Bloodthirster flapping their wings, let alone actually trying to kill someone, with Thorgrim, scaling to Ungrim Ironfist who is definitively superior to Daemonslayers, who are themselves comparable to Greater Daemons like Bloodthirsters (hence the name), adding onto this, he should scale to Sigvald the Magnificent who was able to one-shot a powerful Daemon Prince, who at the very least is slightly superior to Greater Daemons. So AP is probably moot.
When it comes to sensing stuff like fears or concerns, that's going to be pretty null when it comes to Throgrim, as not only has he never really felt afraid throughout his entire career even when threatened and in very dire circumstances, his Crown and it's runes completely remove his fears, only giving him complete and utter certainty in his actions as the High King of the Dwarfs. The Great Book of Grudges only reinforces this as probably the most Asta is gonna sense emotion-wise is unrelenting willpower and rage.
As for skill wise, Thorgrim scales in skill to Ungrim Ironfist and Gotrek Gurnisson, who are INSANELY skilled, being fully capable of bullying Bloodthirsters who are master combatants and have pretty strong analaytical prediction, information analysis and enhanced senses (ironically Witchsight is very similar to Asta's senses, detecting thoughts, predicting moves, sensing emotions and intentions etc etc) not to mention fighting people with actual precognition and still outskilling. Alongside this, scaling him back again to Sigvald, who is such a skilled sword fighter that he was able to literally dance through a gigantic army of Khornate Champions who are comparable stat wise and are master combatants in their own right, and just....shredding them with his sword to the point where not only could they not touch him....but their BLOOD didn't even manage to splatter on him at any point.
Thorgrim is also a fairly tactical fighter, knowing full well how strong his armour, usually redirecting attacks to it if he can't block or parry it outright, making it all the harder to actually strike somewhere that isn't armoured.
