We are not currently selling Hack & Slash. The HARP Fantasy redesign team attempted to fix the incompatibility of the Hack&Slash attack tables with standard scaling of elemental attack spells but none of the low effort solutions worked out. If they had, we would have included it as part of the new enhanced Martial Law. Unfortunately they did not. We suspect that the only way of fixing Hack & Slash in this regard is to totally rewrite its tables, so we've put it back on the shelf and will revisit the idea of additional combat options at a later date.
Physical copies of the Bazaar Annual can be bought still from some (online) game stores.
Best wishes,
Nicholas
