So I am coming around on Silas, the same way I did on Mary, and for the same reason: more cards were released in their campaigns, and those cards play to their strengths.
Many new cards, like signum crucis (now 0xp), give you benefits before you commit them. That allows you to add a ton of bless tokens to the bag every round, either for one action or as part of the mythos phase, and with Drawing Thin, the numbers can get substantial. In a bless-heavy strategy, Unrelenting can either majorly increase your chances of success (Most of the tokens that would make you fail, including numerical tokens, out of the bag), or you can put additional blessings on it, draw cards, and let it ride.
Silas can supplement his stats in odd ways with level two Defiance, Steadfast, or advanced Guts/Manual dexterity. Want to spend money as fast as you make it? Use inspiring presence with Madame LeBranche to power either dark horse or the Mariner's compass. There’s even solo potential, with the compass, sharp vision, and Granny Orne, true understanding, or the survivor suite of fail-to-win.
I am playing with Silas and Ursula through TIC currently*, and speed is more important than the ability to dole out violence. Track shoes, quick thinking to grab enemies off of pals during their turn...it's Arkham at a sprint!
I’ve left my previous review below, but consider this one the most accurate.
*We won.
Old review:
[[[Silas is a signature character for the Innsmouth Conspiracy. For a cycle all about bless tokens, it’s currently hard to pin down if he can do much that’s more effective than William Yorrick.
Obviously, Marsh will have a better time with the frequent dex checks the campaign asks for. But six boxes into the game’s life, survivors have slim pickings in terms of weapons, and if you don’t buy the Stella set, you’re stuck with the old hunting rifle and that’s about it. (Silas could be confident with the bow, running shoes, Peter, and even Dark Horse, but he has no additional action economy to make the bow effective.)
Being able to second-guess skill checks is useful, but it’s extremely hard to build out combat versatility without guardian access. Your ability to boost your attack and to do extra damage is minimal.]]]
If you want to play as Silas, try the Eldritch Horror third edition expansion, where one of his items is a shirt that keeps getting torn off.
