Phew, finally finished this after giving up on it a few times - I actually mastered it about a month ago but decided to come back and finish off the last few post mastery rooms.
Firstly to point out the obvious, this is a tough hold - I'd put it on a par difficulty-wise with Perfection so if you're an not experienced player then don't expect to get too far (although there are H&S topics for most rooms).
Onto the puzzles themselves, the first level gives a good taste of what's to come including some particularly nasty rooms where you need to manipulate goblins using decoys and disarm tokens. Moving on you'll be handling giants and rock golems and you'll need to know some of the peculiarities of giant behaviour as a number of rooms have you manoeuvering them through pressure plate mazes. The lava gates level forces sword position and movement with more monster manoeuvering under these conditions. The final level will have you juggling mimics, clones & decoys in some of the hardest rooms in the hold. This makes it sound quite linear in nature but it's not - you'll be revisiting levels from different places in order to progress and the northern part of the lava gates features a quite superb meta-puzzle where you'll navigate a number of rooms with differing sword positions. As well as this, there's also a hidden level called Hordes (aptly named) as well as a post mastery level featuring even harder versions of some of the previous rooms.
Although the majority of the puzzles are based on manipulation, on the whole I felt there was a decent variety if maybe some repetition, particularly on the giant/pressure plate mazes but I found the level of difficulty did seem to increase as I progressed.
The design of the hold is superb, especially for The Complex & The Lava Gates - I was actually a bit disappointed at the end that I couldn't have gone back through The Complex using the tunnels and passages that were dotted around.
The voice acting is also excellent, especially Ombus. I realize it costs extra to bring in vocal talent from outside the community but it really adds to the experience. The issue of the scrolls has already been mentioned - hopefully this will be improved in the next release? (scrolling scrolls perhaps?)
Overall this is a fantastic addition to the Smitemaster's Selection collection and probably my favourite of them all.
My Verdict:
Difficulty: 8.5
Fun: 10

)... But those goblin-and-decoys rooms were EVIL! 
Of course, I had to use H&S to complete them. The ideas of those rooms are good, but the way goblins react on multiple decoys is something that I don't really understand, so these rooms were quite trial-and-error for me.
