[HoMM V]9 Race - Swamp! Is it needed?

I listened to Veta and added totems to the Bogfolk and made some changes to the entire race.
Tear of Ashi – Carnivorous Plant (+20% Water magic power, everything else remains the same).
Specialized building – Totem Hut. Allows the Bogfolk hero to buy totems for Bogfolk creatures. Bogfolk Totems: Bear Totem +3 hit points, Eagle Totem +10% to initiative, Lynx Totem +1 to speed, Fox Totem +2 defense, Wolf Totem +2 attack. Each totem costs 1000 gold, and only one totem can be given to each creature (and only to Bogfolk creatures). – 3000, 5 mercury, and 5 sulfur.
Bogfolk Slowdown!
Totem Power - +50% to totem power.
Bogland – -1 to the speed of all enemy creatures.
Bog Magic – Gives the Bogfolk hero the Bog Magic spell, which gives -5% initiative to enemy creatures and +5% to friendly creatures. Lasts 5 turns + 0.5 * hero level. Costs 0 mana.
Super ability –> “Power of the Bog” – Gives the Hero +100% damage from Water magic and +50% totem power. Also improves the Bog Magic spell, giving an additional -5% initiative to the enemy and +5% initiative to friendly creatures.
To develop to the super ability, you need: Chaos Magic – Wrath of Water, Leadership – Aura of Speed, Attack – Cold Steel, Ice Arrows.
Talas – Totemist. (Further strengthens totems by 50%).
The top part has also been changed (the creatures have not been changed). What do you think?:)
