First, to be clear, Sir Lora is not a full-fledged companion, he's really just a chatty pet. I mention this not because I expected a proper, fleshed-out companion, but because the description of the DLC might be misleading to some. The only benefits he provides, apart from the flavor aspect, are a few unremarkable crafting recipes he'll intermittently supply via dialogue as the main story progresses. In support of this content, I'll admit that the character concept of a quixotic squirrel knight riding a skeletal cat is fun in a quirky way, his dialogue is occasionally amusing, and the quality of the voice acting is superb. The AI, however, is so ridiculously, obnoxiously, inexcusably stupid that I think the game is frankly just a more pleasant experience without this DLC installed. Sir Lora will not only fail to avoid traps and harmful surfaces and clouds, he'll actively walk straight into them, repeatedly, even when your main character is standing still. I've seen him just path blithely straight into death fog and instantly die. Unfortunately, there's no way to control his movement patterns if you let him follow you. Mercifully, he scampers off during combat, though sometimes, depending on terrain, he still won't move far enough away and ends up taking incidental damage from enemy AoE. If he was deliberately designed to be suicidal, then job well done, I suppose, though I seriously question the wisdom of such a design choice. If he wasn't, the AI programmer responsible has some explaining to do. You're not missing much if you buy this DLC; save yourself a potential headache and do so only if you're just looking for an excuse to throw some money at Larian.
