the question is this;
My DM fudges dice rolls(pretty obviously but claims he doesn't) and hates SoS/SoD/SoL spells, preferring HP damage which he supports by stating monster weaknesses as "Damage" regardless of knowledge check. So my SoS spells rarely(to the point of almost never) ever land, regardless of the odds, if they are cast against anything that could be considered a threat.
How can I build this character going forward to make it less reliant on SoS spells, considering that we never find scrolls that I could scribe into my spellbook, liquid funds are a rarity, and purchasing spells is situational at best?
