Concerning spells, I have implemented all druid spells of level 1, 2, 3 and 4 plus some of the spells of level 5. Please see the Druid's spell list below and for the updated spell descriptions, see the Druid's webpage. I have found that the spells that take the most time to implement are spells that affect terrain like Quicksand, Insect Plague, etc. Because there is both the immediate effect of the spell and then everything else associated with the new terrain. As you can see in one of the screenshots below, squares can contain up to two effects, one on the ground (Spike Growth in the picture) and one in the air (Insect Plague in the picture).



Among the spells I implemented, the ones that may be the most interesting are Gust of Wind and Greater Gust of Wind. They push creatures back by a few squares, so it's nice to use in conjunction with dangerous terrain or terrain spells. Also, it will be fun to watch the computer use those spells smartly against the player.

Concerning summon spells, I've implemented all summon spells in the Druid's spell list. I'm thinking to add a 'Summon Monster' line of spells for the Wizard. I expect that it will include the following: Summon Skeleton at level 1, Summon Slime at level 2, Summon Gargoyle at level 3, Summon Babau at level 4, Summon Ettin at level 5, Summon Vrock at level 6, Summon Stone Golem at level 7, Summon Iron Golem at level 8 and Summon Marilith at level 9. There will be a gold and XP cost for the higher levels.​
