There is no definitive answer to this question, as it depends on the player’s personal preferences. However, some factors that could influence this decision include the player’s budget, how often they plan to use their shield, and whether they feel that a hero shield offers more protection than a frozen shield. In general, frozen shields are generally considered to be less effective than hero shields due to their lower damage output and lack of protection. However, if the player is looking for a more reliable shield that can be used frequently, then a frozen shield may be the better option.
