I'm not sure about about Liquid Courage for many of the investigators in the core set/Dunwich legacy. To be honest, the investigators who struggle with Sanity - e.g. Roland Banks, or "Skids" O'Toole - also tend to have low willpower, so this isn't so useful for them.

Zoey Samaras can make pretty good use of it, particularly if she has something to give Willpower a boost, and her sanity is low enough to need a little help.

However, I've found it fantastic for... Agnes Baker. Yes, she can't actually take this card herself - but another investigator can, and then use liquid courage to heal Agnes' horror. This lets her use her ability to inflict damage when she takes horror even more often, which is awesome, and her 5 makes it unlikely that she'll fail the test to heal the second horror very often.

So if you're hunting Great Old Ones with Agnes at your side, embrace sociable investigating! Come 'ere Agnes, and have wee dram for yer nerves...

This is an cheap (if clunky) option for horror healing that gains new life as a combo piece for "by-two" Rogues. The ability to trigger an easy test at will provides fodder for "Watch this!" and Lucky Cigarette Case - in combination with Double or Nothing and a willpower talent, a rogue can potentially win six cash in a single test of whiskey-shooting ability.

On a separate note, I absolutely love that the cards for drinking, smoking, and gambling all work together to promote a play style based on risk-taking - what a resonant design!

There's a fun place for this in a Finn Edwards's deck that is using Fence, not to use it himself but in a support role, dishing out invigorating shots to colleagues with high enough willpower. It may only be a consideration late in the campaign when your deck is already well-tuned and you have Adaptable to bring it in or if you are working with someone who you know will always be on the edge when it comes to sanity.
